General Description

The VHCT540A 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 dissipation.

The VHCT540A 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: tPD=5.4ns (Typ.) at Vcc=5V

■ Low Power Dissipation: ICC= 4µA (Max.) at Ta= 25°C

■ Power down protection is provided on all inputs and outputs

■ Pin and function compatible with 74HCT540
