74HC257 IC - (SMD Package) - Quad 2-input multiplexer IC (74257 IC)

The 74HC257 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.

Features:-

• Non-inverting data path

• 3-state outputs interface directly with system bus

• Complies with JEDEC standard no. 7A

• Input levels:

- For 74HC257: CMOS level

- For 74HCT257: TTL level

• ESD protection:

- HBM JESD22-A114F exceeds 2000 V

- MM JESD22-A115-A exceeds 200 V

• Multiple package options
