HC158 QUAD 2 CHANNEL MULTIPLEXER INV. HC157 QUAD 2 CHANNEL MULTIPLEXER

DESCRIPTION The M54/74HC157 and the M54/74HC158 are high speed CMOS QUAD 2-CHANNEL MULTIPLEXER’s fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. ■ HIGH SPEED tPD = 10 ns (TYP.)

HC258QUAD 2CHANNEL MULTIPLEXER 3-STATE, INVERTING HC257 QUAD 2 CHANNEL MULTIPLEXER 3-STATE

DESCRIPTION The M54/74HC257 and the M54/74HC258 are high speed CMOS MULTIPLEXERs fabricated with silicon gate C2MOS technology. They have the same high speed performance ofLSTTL combined with true CMOS low power consumption. ■ HIGH SPEED tPD = 10 ns (TYP.) at VCC = 5 V ■ LOW POWER DISSIPATION
