Description

The M54/74HC257 and the M54/74HC258 are high speed CMOS MULTIPLEXERs fabricated with silicon gate C2MOS technology.

M54/74HC257 and the M54/74HC258 have the same high speed performance of LSTTL combined with true CMOS low power consumption.

These M54/74HC257 and the M54/74HC258 IC's are composed of an independent 2- channelmultiplexer with commonSELECT and ENABLE INPUT.

The M54/74HC258 is an inverting multiplexer while the M54/74HC257 is a non-inverting multiplexer. When theENABLE INPUTis held "High", outputs of both IC's become high-impedance state. If SELECT INPUT is held "Low", "A" data is selected, when SELECT INPUT is high "H", "B" data is chosen.

M54/74HC257 and the M54/74HC258 All inputs are equipped with protection circuits against static discharge and transient excess voltage.
