74VHC244

Octal Buffer/Line Driver with 3-STATE Outputs

General Description

Features

The VHC244 is an advanced high speed CMOS octal bus

buffer fabricated with silicon gate CMOS technology. It

achieves high speed operation similar to equivalent Bipolar

Schottky TTL while maintaining the CMOS low power dissi-

pation. The VHC244 is a non-inverting 3-STATE buffer hav-

ing two active-LOW output enables. These devices are

designed to be used as 3-STATE memory address drivers,

clock drivers, and bus oriented transmitter/receivers.

■ High Speed: t_PD3.9ns (typ) at V_CC5V

■ High noise immunity: V_NIHV_NIL28% V_CC(min)

■ Power down protection is provided on all inputs

■ Low noise: V_OLP0.6V (typ)

■ Low power dissipation: I_CC

4 A (max) @ T_A25 C

■ Pin and function compatible with 74HC244

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

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 back up. This cir-

cuit prevents device destruction due to mismatched supply

and input voltages.
