TC74AC257P, TC74AC258P
The TC74AC257 and TC74AC258 are advanced high speed CMOS MULTIPLEXERs fabricated with silicon gate and double-layer metal wiring C2MOS technology.
They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
Each is posed of four independent 2-channel multiplexers with mon SELECT and OUTPUT ENABLE ( OE ).
The TC74AC257 is a non-inverting multiplexer, while the TC74AC258...
