74HCT251 - 8-input multiplexer

Download the 74HCT251 datasheet PDF (74HC251 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for 8-input multiplexer.

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).

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.
