74HC257DB - Quad 2-input multiplexer; 3-state

Quad 2-input multiplexer; 3-state - The 74HC257; 74HCT257 is a quad 2-input multiplexer with 3-state outputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. ·Non-inverting data path\n·3-state outputs interface directly with system bus\n·Complies with JEDEC standard no. 7A\n·Input levels:·For 74HC257: CMOS level\n·For 74HCT257: TTL level;
