IC logic family and types

IC logic family is a group of compatible IC’s with the same logic levels and supply voltages for performing various logic functions have been fabricated using a specific circuit configuration.

Types of logic families

There are two types of logic families. These are –

1. Bipolar logic family
2. Unipolar logic family

Bipolar logic families are of two types.

i) Saturated logic families: RTL, DTL, HTL, TTL etc.

ii) Non-saturated families: Scotty TTL, Emitter Coupled logic (ECL)

Unipolar logic families have several types like as –

i) PMOS

ii) NMOS

iii) CMOS.
