The M54/74HCT257 and the M54/74HCT258 are high speed CMOS MULTIPLEXERs fabricated with silicon gate C2MOS technology.
They have the same high speed performance of LSTTL bined with true CMOS low power consumption.
These IC’s are posed of an independent 2channel multiplexer with mon SELECT and ENABLE INPUT.
