DESCRIPTION
The M54/74HCT257 and the M54/74HCT258 are
highspeed CMOSMULTIPLEXERsfabricated with
silicon gate C
2
MOS technology.
They have the same high speed performance of
LSTTL combined with true CMOS low power con-
sumption.
These IC’s are composed of an independent 2-
channelmultiplexer with commonSELECT and EN-
ABLE INPUT.
The M54/74HCT258 is an inverting multiplexer
while the M54/74HCT257 is a non-inverting multi-
plexer. When the ENABLE INPUT is held ”High”,
outputs of both IC’sbecome high-impedance state.
If SELECTINPUTisheld”Low”,”A” dataisselected,
when SELECT INPUT is high ”H”, ”B” data is
chosen.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
This integrated circuit has input and output charac-
teristics that are fully compatible with 54/74 LSTTL
logic families. M54/74HCT devices are designed to
directly interface HSC
2
MOS systems with TTL and
NMOS components. They are also plugin replace-
