M54HC258 - QUAD 2-CHANNEL MULTIPLEXER
The M54/74HC257 and the M54/74HC258 are high speed CMOS MULTIPLEXERs fabricated with sili2 con gate C MOS technology.
They have the same high speed performance of LSTTL combined with true CMOS low power consumption.
These IC’s are composed of an independent 2channel multiplexer with common SELECT an
