74HC257PW - Quad 2-input multiplexer

Download the 74HC257PW datasheet PDF. This datasheet also covers the 74HC257 variant, as both devices belong to the same quad 2-input multiplexer family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • Wide supply voltage range from 2.0 V to 6.0 V.
  • CMOS low power dissipation.
  • High noise immunity.
  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.
  • Complies with JEDEC standards:.
  • JESD8C (2.7 V to 3.6 V).
  • JESD7A (2.0 V to 6.0 V).
  • Non-inverting data path.
  • 3-state outputs interface directly with system bus.
  • Input levels:.
  • For 74HC257: CMOS level.
  • For 74HCT257: TTL level.
