74VHCT244A

Octal Buffer/Line Driver with 3-STATE Outputs

due to mismatched supply and input/output voltages. This

General Description

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

The VHCT244A is an advanced high speed CMOS octal

bus transceiver fabricated with silicon gate CMOS technol-

ogy. It achieves high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low

power dissipation. The VHCT244A is a non-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.

Features

■ High Speed: t_PD= 5.9 ns (typ) at V_CC= 5V

■ Power down protection is provided on inputs and

outputs

■ Low power dissipation: I_CC= 4 µA (max) @ T_A= 25°C

■ Pin and function compatible with 74HCT244

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

the input and output (Note 1) pins without regard to the

supply voltage. These circuits prevent device destruction
