The HC280 and HCT280 are 9-bit odd/even parity, generator checker devices. Both even and odd parity outputs are available for checking or generating parity for words up to nine bits long. Even parity is indicated (E output to any input of an additional HC/HCT280 parity checker.

Typical Propagation Delay = 17ns at V_CC = 5V, C_L = 15pF, T_A = 25°C
Replaces LS180 Types
Easily Cascadable
Fanout (Over Temperature Range)
