74VHC541

Octal Buffer/Line Driver with 3-STATE Outputs

An input protection circuit insures that 0V to 7V can be

General Description

applied to the input pins without regard to the supply volt-

age. This device can be used to interface 5V to 3V systems

and two supply systems such as battery backup. This cir-

cuit prevents device destruction due to mismatched supply

and input voltages.

The VHC541 is an advanced high-speed CMOS device

fabricated with silicon gate CMOS technology. It achieves

the high-speed operation similar to equivalent Bipolar

Schottky TTL while maintaining the CMOS low power dissi-

pation.

The VHC541 is an octal buffer/line driver designed to be

employed as memory and address drivers, clock drivers

and bus oriented transmitter/receivers.

Features

■ High Speed: t_PD3.5 ns (typ) at V_CC5V

■ Low power dissipation: I_CC

4 A (max) at T_A25 C

This device is similar in function to the VHC244 while pro-

viding flow-through architecture (inputs on opposite side

from outputs). This pinout arrangement makes this device

especially useful as an output port for microprocessors,

allowing ease of layout and greater PC board density.

■ High noise immunity: V_NIHV_NIL28% V_CC(min)

■ Power down protection is provided on all inputs

■ Low noise: V_OLP0.9V (typ)

■ Pin and function compatible with 74HC541
