MARKING DIAGRAMS

General Description

The MM74HCT540 and MM74HCT541 3−STATE buffers utilize

advanced silicon−gate CMOS technology and are general purpose

high speed inverting and non−inverting buffers. They possess high

drive current outputs which enable high speed operation even when

driving large bus capacitances. These circuits achieve speeds

comparable to low power Schottky devices, while retaining the low

power consumption of CMOS. Both devices are TTL input compatible

and have a fanout of 15 LS−TTL equivalent inputs.

MM74HCT devices are intended to interface between TTL and

NMOS components and standard CMOS devices. These parts are also

plug−in replacements for LS−TTL devices and can be used to reduce

power consumption in existing designs.

(Note: Microdot may be in either location)

The MM74HCT540 is an inverting buffer and the MM74HCT541 is

a non−inverting buffer. The 3−STATE control gate operates as a

two−input NOR such that if either G1 or G2 are HIGH, all eight

outputs are in the high−impedance state.

Pin Assignment for SOIC and TSSOP

In order to enhance PC board layout, the MM74HCT540 and

MM74HCT541 offers a pinout having inputs and outputs on opposite

sides of the package. All inputs are protected from damage due to

static discharge by diodes to V and ground.

Features

• TTL Input Compatible

• Typical Propagation Delay: 12 ns

• 3−STATE Outputs for Connection to System Buses

• Low Quiescent Current: 160 ꢀ A

• Output Current: 6 mA (min)

• These are Pb−Free Devices
