HD74HC678, 16-bit Address Comparator

The HD74HC678 address comparator simplifies addressing of memory boards and/or other peripheral devices.

The four P inputs are normally hard wired with a preprogrammed address.

An internal decoder determines what input information applied to the 16 A inputs must be low or high to cause a low state a

HD74HC678 Features

* a transparent latch and a latch enabled input (C). When C is high, the device is in the transparent mode. When C is low, the previous logic state of Y is latched. Features

* High Speed Operation High Output Current: Fanout of 10 LSTTL Loads Wide Opera
