74VHC240

Octal Buffer/Line Driver with 3-STATE Outputs

General Description

Features

The VHC240 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 VHC240 is an inverting 3-STATE buffer having

two active-LOW output enables. This device is designed to

drive buslines or buffer memory address registers.

■ High Speed: t_PD3.6ns (typ) at T_A25 C

■ Low power dissipation: I_CC

4 A (max) @ T_A25 C

■ High noise immunity: V_NIHV_NIL28% V_CC(min)

■ Power down protection is provided on all inputs

■ Low noise: V_OLP0.9V (max)

■ Pin and function compatible with 74HC240

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 backup. This cir-

cuit prevents device destruction due to mismatched supply

and input voltages.
