HD74HCT688

8-bit Magnitude Comparator

Description

The HD74HCT688 compares bit for bit two 8-bit words and indicate 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

•

LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility

High Speed Operation: t

(Data to
