DESCRIPTION

The M54/74HC240HV and HC241HV are high
speed CMOSOCTAL BUSBUFFERs fabricated in
silicongate C2MOS technology.

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 whichallows all inputs tobedriven by

logic levels exceedingthe 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.
