Choosing Between TTL & CMOS for Your Digital Logic Design
There are two families of logic devices called TTL and CMOS. For those who are new to these devices, TTL stands for transistor transistor logic devices and CMOS for complementary metal-oxide semiconductor devices. Bipolar junction transistors are the building blocks for TTL logic, whereas MOSFETs are the building blocks for CMOS logic. Usually, any combinational…

Transistor Transistor Logic (TTL)
Transistor transistor logic (TTL) is a logic family implemented with bipolar process technology that combines or integrates NPN transistors, PN junction diodes and diffused resistors in a single monolithic structure to get the desired logic function. The NAND gate is the basic building block of this logic family. We have different subfamilies in this logic…
