DM74S473

(512 x 8) 4096-Bit TTL PROM

General Description

This Schottky memory is organized in the popular 512

words by 8 bits configuration A memory enable input is pro-

vided to control the output states When the device is en-

abled the outputs represent the contents of the selected

word When disabled the 8 outputs go to the ‘‘OFF’’ or high

impedance state

PROMs are shipped from the factory with lows in all loca-

tions A high may be programmed into any selected location

by following the programming instructions
