74F401 CRC Generator/Checker April 1988 Revised August 1999 74F401 CRC Generator/Checker General Description Features The 74F401 Cycle Redundancy Check (CRC) Generator/ � Eight selectable polynomials Checker provides an advanced tool for implementing the � Error indicator most widely used error detection scheme in serial digital � Separate preset and clear controls data handling systems. A 3-bit control input selects one-of- � Automatic right justification eight generator polynomials. The list of polynomials includes CRC-16 and CRC-CCITT as well as their recipro- � Fully compatible with all TTL logic families cals (reverse polynomials). Automatic right justification is � 14-pin package incorporated for polynomials of degree less than 16. Sepa- � 9401 equivalent rate clear and preset inputs are provided for floppy disk � Typical applications: and other applications. The Error output indicates whether Floppy and other disk storage systems or not a transmission error has occurred. Another control input inhibits feedback during check word transmission. Digital cassette and cartridge systems The 74F401 is fully compatible with all TTL families.
