(512 x 8) 4096-Bit TTL PROM

General Description

Features

Advanced titanium-tungsten (Ti-W) fuses

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.

Schottky-clamped for high speed

Address accessÐ45 ns max

Enable accessÐ30 ns max

Enable recoveryÐ30 ns max

PNP inputs for reduced input loading

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.

All DC and AC parameters guaranteed over
