74F401
CRC Generator/Checker
General Description
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.
