74VHCT245A

Octal Buffer/Line Driver with 3-STATE Outputs

Features

General Description

■ High Speed: t = 5.4ns (Typ.) at V = 5V

The VHCT245A is an advanced high speed CMOS octal

bus transceiver fabricated with silicon gate CMOS tech-

nology. It achieves high speed operation similar to equiv-

alent Bipolar Schottky TTL while maintaining the CMOS

low power dissipation. The VHCT245A is intended for

bidirectional asynchronous communication between

data busses. The direction of data transmission is deter-

mined by the level of the T/R input. The enable input can

be used to disable the device so that the busses are

effectively isolated.

■ Power Down Protection on Inputs and Outputs

Low Power Dissipation: I_CC= 4µA (Max.) @ T_A= 25°C

■

■ Pin and Function Compatible with 74HCT245

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
