M74HC298 QUAD 2 CHANNEL MULTIPLEXER/REGISTER

The M54/74HC298 is a high speed CMOS QUAD 2CHANNEL MULTIPLEXER/REGISTER fabricated in silicon gate C 2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. These circuits are controlled by the signals WORD SELECT and CLOCK. When the WORD SELEC.
