M54HC258 Description
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 bined with true CMOS low power consumption. These IC’s are posed of an independent 2channel multiplexer with mon SELECT and ENABLE INPUT.
