DESCRIPTION

The M54/74HC240HV and HC241HV are high

speed CMOS OCTAL BUS BUFFERs fabricated in

silicon gate C

They have the same high speed performance of

LSTTL combined with true CMOS low power

consumption.

Performing the same

function of their non HV

counterpart,

they

have

a

particularl

input

configuration which allows all inputs to be driven by

logic levels exceeding the supply voltage.

This makes them particularly suitable in systems

where mixed 3V/5V logic devices need to be

interfaced.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.

NOTE: BOTH DEVICES DO NOT MEET 2KV ESD
