描述 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.

特性 Features

• High Speed Operation: tpd (P or Q to Output) = 17 ns typ (CL = 50 pF)

• 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)
