TC74HC280AF Description

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC280A is posed of nine data inputs A thru I and odd/even parity outputs Σ ODD and Σ EVEN. The odd parity output is high when an odd number of data inputs are high.
