DESCRIPTION

The M54/74HC240HV and HC241HV are high

speed CMOS OCTAL BUS BUFFERs fabricated in

silicon gate C²MOS technology.

logic levels exceeding the supply voltage.

This makes them particularly suitable in systems

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

interfaced.

They have the same high speed performance of

LSTTL combined with true CMOS low power

consumption.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.

Performing the same function of their non HV

counterpart, they have

configuration which allows all inputs to be driven by

particularl input

NOTE: BOTH DEVICES DO NOT MEET 2KV ESD
