74HC180 Datasheet | Hitachi Semiconductor

Description This universal, monolithic, 9-bit (8 data bits plus 1 parity bit) parity generator/checker features odd/even outputs and control inputs to facilitate operation in either odd or even parity applications. Depending on whether even or odd parity is being generated or checked, the even or odd inputs can be utilized as the parity of 9th-bit input. The wordlength capability is easily expanded by cascading. Features - High Speed Operation: - High Output Current: Fanout of 10 LSTTL Loads - Wide Operating Voltage: VCC = 2 to 6 V - Low Input Current: 1 µA max - Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table Inputs ∑ of H’s at A Thru H Even Even Odd H Even Odd L Odd L L H H H L Outputs ∑ Even H L L H L H ∑ Odd L H H L L H HD74HC180 Pin Arrangement G1 Inputs H2 Inputs Even Odd 3 4 Outputs Σ Even Σ Odd 5 6 GND 7 Logic Diagram Even Odd G...
