DS1628DS3628 Octal TRI-STATE

MOS Drivers

General Description

The DS1628DS3628 are octal Schottky memory drivers

with TRI-STATE outputs designed to drive high capacitive

loads associated with MOS memory systems The drivers’

output (VOH) is specified at 34V to provide additional noise

immunity required by MOS inputs A PNP input structure is

employed to minimize input currents The circuit employs

Schottky-clamped transistors for high speed A NOR gate of

two inputs DIS1 and DIS2 controls the TRI-STATE mode
