CRC Generator/Checker

General Description

Features

The 74F401 Cycle Redundancy Check (CRC) Generator/

Checker provides an advanced tool for implementing the

most widely used error detection scheme in serial digital

data handling systems. A 3-bit control input selects one-of-

eight generator polynomials. The list of polynomials

includes CRC-16 and CRC-CCITT as well as their recipro-

cals (reverse polynomials). Automatic right justification is

incorporated for polynomials of degree less than 16. Sepa-

rate clear and preset inputs are provided for floppy disk

and other applications. The Error output indicates whether

or not a transmission error has occurred. Another control

input inhibits feedback during check word transmission.

The 74F401 is fully compatible with all TTL families.
