74HCT251 - 8-input multiplexer

Download the 74HCT251 datasheet PDF. This datasheet also covers the 74HC251 variant, as both devices belong to the same 8-input multiplexer family and are provided as variant models within a single manufacturer datasheet.

Description

The 74HC251; 74HCT251 is an 8-bit multiplexer with eight binary inputs (I0 to I7), three select inputs (S0 to S2) and an output enable input (OE).

The select inputs select one of the eight binary inputs and route it to the complementary outputs (Y and Y).

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).
  • Input levels:.
  • For 74HC251: CMOS level.
  • For 74HCT251: TTL level.
  • Non-inverting data path.
  • ESD protection:.
  • HBM JESD22-A114F exce.

74HC251; 74HCT251 8-input multiplexer; 3-state Rev. 6 — 8 February 2021 Product data sheet 1. General description The 74HC251; 74HCT251 is an 8-bit multiplexer with eight binary inputs (I0 to I7), three select inputs (S0 to S2) and an output enable input (OE). The select inputs select one of the eight binary inputs and route it to the complementary outputs (Y and Y). A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits • Wide supply voltage range from 2.0 V to 6.
