DS16149/DS36149, DS16179/DS36179 Hex MOS Drivers

General Description

Features

High speed capabilities

The DS16149/DS36149 and DS16179/DS36179 are Hex

MOS drivers with outputs designed to drive large capacitive

loads up to 500 pF associated with MOS memory systems.

PNP input transistors are employed to reduce input currents

allowing the large fan-out to these drivers needed in memo-

ry systems. The circuit has Schottky-clamped transistor log-

ic for minimum propagation delay, and a disable control that

places the outputs in the logic ‘‘1’’ state (see truth table).

This is especially useful in MOS RAM applications where a

set of address lines has to be in the logic ‘’1’’ state during

refresh.

Typ 9 ns driving 50 pF

Typ 29 ns driving 500 pF

Built-in 15 X damping resistor (DS16149/DS36149)

Same pin-out as DM8096 and DM74366

The DS16149/DS36149 has a 15 X resistor in series with

the outputs to dampen transients caused by the fast-switch-

ing output. The DS16179/DS36179 has a direct low imped-

ance output for use with or without an external resistor.
