TC74AC258FN Description
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 is an inverting.
