TC74VHC257FN Description
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It is posed of four independent 2-channel multiplexers with mon SELECT and OUTPUT ENABLE ( OE ). If OE is set low, the outputs are held in a high-impedance state.
TC74VHC257FN Key Features
