M74HCT158 QUAD 2 CHANNEL MULTIPLEXER

The M54/74HCT157 and the M54/74HCT158 are high speed CMOS QUAD 2-CHANNEL MULTIPLEXERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. These devices consist of four 2-input digital multi.
