Serial Data Polynomial Generator/Checker
General Description
The 74F402 expandable Serial Data Polynomial generator/
checker is an expandable version of the 74F401. It pro-
vides an advanced tool for the implementation of the most
widely used error detection scheme in serial digital han-
dling systems. A 4-bit control input selects one-of-six gen-
erator polynomials. The list of polynomials includes CRC-
16, CRC-CCITT and Ethernet , as well as three other
standard polynomials (56
Individual clear and preset inputs are provided for floppy
disk and other applications. The Error output indicates
whether or not a transmission error has occurred. The
CWG Control input inhibits feedback during check word
transmission. The 74F402 is compatible with FAST
devices and with all TTL families.
