74VHCT240A

Octal Buffer/Line Driver with 3-STATE Outputs

Features

General Description

■ High Speed: t = 5.6ns (Typ.) at V = 5V

The VHCT240A is an advanced high speed CMOS octal

bus transceiver fabricated with silicon gate CMOS

technology. It achieves high speed operation similar to

equivalent Bipolar Schottky TTL while maintaining the

CMOS low power dissipation. The VHCT240A is an

inverting 3-STATE buffer having two active-LOW output

enables. This device is designed to be used as 3-STATE

memory address drivers, clock drivers, and bus oriented

transmitter/ receivers.

■ Power down protection is provided on inputs and

outputs

■ Low power dissipation: I = 4µA (Max.) @ T = 25°C

■ Pin and function compatible with 74HCT240

Protection circuits ensure that 0V to 7V can be applied to

(1)

the input and output pins without regard to the supply

voltage. These circuits prevent device destruction due to

mismatched supply and input/output voltages. This

device can be used to interface 5V to 3V systems and

two supply systems such as battery back up.

Note:

1. Outputs in OFF-State
