DS1628/DS3628 Octal TRI-STATEÉ MOS Drivers
General Description
The DS1628/DS3628are octal Schottky memory drivers
with TRI-STATE outputs designedto drive high capacitive
loads associated with MOS memory systems. The drivers’
output (VOH)is specifiedat 3.4Vto provide additional noise
immunity requiredby MOS inputs.A PNP input structureis
employedto minimize input currents. The circuit employs
Schottky-clamped transistors forhigh speed.A NOR gateof
two inputs, DIS1and DIS2, controlsthe TRI-STATE mode.
