The operating temperature for standard commerdcial TTL (74 series) 0 to 70 degrees Celsius. Military grade between -40 and 125 degrees. Some commercial 74 series used for industrial and automotice applications between -15 and 85 degrees C. In the real world standard commercial TTL often works quite happily under mil spec conditions. I know because I have tried it!

What is the operating temperature for the 1500 kva diesel generator?

The operating temperature for a 1500 kVA diesel generator can vary depending on the specific model and manufacturer. It is important to check the manufacturer's specifications for the specific generator model to confirm its exact operating temperature range.


What does prefix 74 and 54 on a ttl of cmos ic indicate?

The 74 indicates a general use IC, the 54 indicates a military specification device with a greater operating temperature range. These two prefixes were originally assigned in the 1960s by Texas Instruments for their TTL logic family, but have since become de facto industry standards. They were also adopted for CMOS in the 1980s when it was decided that having common package pinouts would make it easier for both logic designers and circuit board layout software.


What is a TTL waveform?

A TTL waveform refers to the output signal of a Transistor-Transistor Logic (TTL) digital circuit, characterized by its distinct voltage levels representing binary states. Typically, a TTL high state is around 2.4 to 5 volts, while a low state is around 0 to 0.8 volts. The waveform transitions sharply between these levels, reflecting the rapid switching behavior of TTL circuits. TTL waveforms are used in various digital applications, including logic gates, microprocessors, and communication systems.

How TTL is operating?

TTL (Time to Live) is reduced by 1 every time a router forwards the packet. The purpose of this is to reduce the negative effects of routing loops. If two routers are misconfigured (it happens) and send a packet back and forth to each other assuming the other router will take care of it, the packet would simply never go away, if it wasn't for TTL. It guarantees that this can only happen a maximum of 256 times (generally quite a bit less). Once that TTL reaches zero, the packet is discarded.

Why when you ping a host in a LAN the TTL value is 128 but if you ping a host in another network the TTL value decreases from 255 to 254 my question is why the TTL value is 128?

The TTL or Time To Live is a value used to make packets eventually die, so they don't end up in infinite loops, clogging the network over time. Certain network devices decrement this value (routers mainly) by one as they process it. When the TTL reaches zero, the packet is discarded. Each Operating System implements its TCP/IP stack differently and starts packets off with the TTL of their choosing (the default TTL of the stack can be changed, but rarely is). Windows is 128 Linux is 64 Cisco is 256 So if your TTL is around 128 (remember the TTL gets decremented by certain devices) you are PROBABLY pinging a windows box. If it's near 256, probably Cisco etc. You can't rely on this information because other network devices can rewrite the TTL in a packet, but it's a decent indication of the OS on the other end, especially if it's a box you own and you aren't going through firewalls etc.
