The 4017 is a 5-stage divide-by-10 "Johnson counter" with 10 decoded outputs
and a carry out bit. The 4000 series are CMOS devices.
In TTL, the 74142 is also designed as a decade counter, which makes it functionally
equivalent to the primary mission of the 4017. But it can't be called "equivalent" in
any other respect, because of the usual wide array of differences in power requirements
and input and output impedances between CMOS and TTL technology.

Features of IC 7447?
The 4017 IC is a decade (divide by ten) counter with decoded outputs. Internally, there is a 4 bit counter, with feedback to reset at 10 instead of 16, followed with a ten output decoder that makes each state available on a separate pin of the IC.Another answerOne of my favorite IC's, the 4017 decade counter/divider.The 4017 takes a clock pulse in and then steps the output from negative to positive in a series of ten steps, with only one pin being on at a time. It has the unique capability of counting up to a certain number and then restarting the count, counting up to a certain number and halting, or it can be cascaded to more 4017's for a higher count.The outputs are labeled 0 through 9. It can sink about 10 ma. of current per pin and is a very versitile IC. It operates from 3 VDC. to 15 VDC.Do a Google search and in parenthesis type in "LM4017". You'll be rewarded with all kinds of technical info which you can download and print.
What is the line of business of TTL?
TTL in the ISO/OSI Stack (IP Networks) ======================= TTL (Time To Live) is the time a message has to live given in hops. Each time the package is forwarded this counter counts down. With the TTL one avoids a datagram being routed in circles and cloaking the "intertube"'s up.
What does the TTLvalue zero indicate?
The TTL (Time To Live) value is a number associated with network routing packets. An information packet will only be forwarded to a certain number of routers before the packet is dropped (deleted). The TTL is a counter decreased by 1 when the packet is forwarded to another router. When the TTL reaches zero, it will not be forwarded to another router.

How important is TTL to network security what is TTL for and can a Hacker use it to harm you PC or network?
TTL stands for "Time To Live". This is a piece of data in a network packet that specifies how many routers the packet can pass through before the packet expires and is thrown away. Every router that the packet travels through subtracts one from the TTL counter. When it reaches zero, the packet expires. The router will drop the packet, and then send a message back to the computer that sent the packet telling it that the packet has expired. The purpose of the TTL counter is to make routing loops less dangerous. Let me explain.... Routers are devices that look at an incoming data packet and decide where to send it to get it one step closer to its destination. It's possible for one or more routers to be configured such that router A sends the packet to router B, which sends it to router C, which sends it to router A, which then starts it over again. Without the TTL counter, this packet (and any subsequent packet sent to the same destination) would circulate endlessly, taking up bandwidth until someone fixes the routing loop. However, with TTL, each router subtracts one from the TTL counter until eventually the counter hits zero and the packet goes away, giving someone time to fix the problem before the links are so congested with looping packets that it's no longer possible to talk to the router. TTL can affect network security in a couple of ways. Most operating systems set the TTL counter to 64 or 128, which is a pretty large number that will guarantee your packet can get across the Internet. To improve your network security, you can set your TTL counter to a low number. If your internal network is only four routers wide, you can set your TTL to 4. This will ensure that any packets generated on your network will not travel very far beyond your internal network. An attacker can also use the TTL feature to probe your network for the existence and address of your routers. This feature is used by the "traceroute" or "tracert" utility. It works by sending out a packet with a TTL of 1. The first router that the packet encounters will decrement the TTL to 0, drop the packet, then send a message to the traceroute program telling it that the packet expired. By looking at the source address of this packet, traceroute knows the address of the first router. Next traceroute sends a packet with a TTL of 2, which causes the packet to expire at the second router, which sends a message back to traceroute and exposing its address. And so on. Once an attacker knows the addresses of your routers, he or she can start working on compromising them, which can cause you no end of security problems. The solution is to prevent these packets from reaching your routers by using a firewall to block them. HTH, Gdunge

Which logic family has the least propagation delay?
Here are the propagation delays for these gatesa) ECL = 2nsb) TTL = 1.5-33ns depending on the type of TTL. Conventional TTL is 9ns, Advanced Schottky TTL is 1.5nsc) RTL = 25nsd) CMOS = 5-20ns depending on if it is conventional CMOS, TTL pin compatible CMOS, high speed TPC CMOS or TTL compatible CMOSSo the fastest would be the Advanced Schottky TTL (74ASxx) at 1.5ns but the choice simply said TTL which I would interpret as Conventional TTL (74xx/54xx) which would have a propagation delay at 9ns.So the winner is ... (a) ECL which has a propagation delay at 2ns.
The main advantage of ECL over TTL?
The main advantage of ECL over TTL is speed.
