HD74HC688

8-bit Magnitude Comparator

Description

The HD74HC688 compares bit for bit two 8-bit words and indicates whether or not they are equal. The

P=Q output indicates equality when it is low.

A single active low enable is provided to facilitate cascading of several packages and enable comparison of

words greater than 8-bits.

This device is useful in memory block decoding applications, where memory block enable signals must be

generated from computer address information.

Features

•

High Speed Operation: t_pd(P or Q to Output) = 17 ns typ (C_L= 50 pF

High Output Current: Fanout of 10 LSTTL Loads

Wide Operating Voltage: V_CC= 2 to 6 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I_CC(static) = 4 µA max (Ta = 25°C)
