ic refers to integrated circuits and ttl refers to transistor transistor logic.
ttl is a family which provides the basic or former structure of logic gates for example different logic gates such as NAND,NOR etc can be made out with the help of transistors connected in a specific manner.
integerated circuits are the combination of logic gates presented on a base with equal number of input pins . for example IC-7408 contains 14 pins
ic 8284
The 7432 is a quad two input OR gate with TTL levels.
This Easy to build PIC based IC tester is very easy to make and highly reliable.This IC tester can successfully check the most of the IC's we are using in our normal project constructions such as TTL,74,74F,CMOS 4000 series.This could be very useful for the professionals as well as hobbyist.
TTL
Compatibility in TTL means that the output of one TTL device can be used to drive the Input of the other TTL device , This because the low and high output window fit inside the low and high input window/profile TTL stand for Transistor Transistor Logic, so any voltage between 0 and 5 volt is compatible where any voltage between 3V and 5V is logic 1 and zero volt is logic 0
ic 8284
Whwn an IC is connected to a PC, then the voltage levels of these two should be synchronized. For this purpose, the TTL voltage level is converted to RS 232 level. RS 232 is the interface between a PC and an IC.
you need some TTL inverter gates.
The 7432 is a quad two input OR gate with TTL levels.
Ttl: 7432, 744075cmos: 4071
naming of IC is done according to manufacturer's name, ic type and IC number. i think MC means motorola is manufacturer. 74 means TTL IC. It is 7408 IC and H means high
TTL 7410CMOS 4023DTL 962/C
Not all the IC's are starts from 74 , it is TTL series IC's starting numbers basically 74 series are digital IC's . GATE FLIP-FLOP COUNTER REGISTER ADDER ALU
TTL 74 86 series or CMOS 4030
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.
Answer"TTL" stands for "Transistor to Transistor Logic". It's a very low current level communication protocol, typically used for very short distances. It also tends to be very sensitive to static and static discharge. It's the communication that is most commonly used between IC chips on a PC board.
The input to the max232 ic will be of Transistor Transistor Logic (TTL) and its voltage range will be of 5 volt. The output of the max 232 ic will be of Recomended Standard 232 Logic (RS232 logic) and its voltage range will be of 12 volt. The max 232 ic which is operating on 5 volt supply has to step up the 5 volt input to 12 volt. Hence a capacitor is used for pumping the voltage and called as pumping capacitor.
