DS1628/DS3628 Octal TRI-STATE MOS Drivers

Features

General Description

The DS1628/DS3628 are octal Schottky memory drivers

with TRI-STATE outputs designed to drive high capacitive

loads associated with MOS memory systems. The drivers’

High speed capabilities

Ð Typical 5 ns driving 50 pF & 8 ns driving 500 pF

TRI-STATE outputs

output (V ) is specified at 3.4V to provide additional noise

High V

(3.4V min)

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.

High density

Ð Eight drivers and two disable controls for TRI-STATE

in a 20-pin package

PNP inputs reduce DC loading on bus lines
