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…
