HD74HC157 - Quad. 2-to-1-line Data Selectors / Multiplexers

General Description

These devices each consist of four 2-input digital multiplexers with common select and strobe inputs.

On the HD74HC157, when the strobe input is at logical “L” the four outputs assume the values as selected from the inputs.

When the strobe input is at a logical “H” the outputs assume logical “L”.

Key Features

  • High Speed Operation: tpd (Data to Output) = 12 ns typ (CL = 50 pF).
  • High Output Current: Fanout of 10 LSTTL Loads.
  • Wide Operating Voltage: VCC = 2 to 6 V.
  • L.

HD74HC157/HD74HC158 Quad. 2-to-1-line Data Selectors / Multiplexers (with noninverted outputs) Quad. 2-to-1-line Data Selectors / Multiplexers (with inverted outputs) REJ03D0578-0200 (Previous ADE-205-454) Rev.2.00 Oct 11, 2005 Description These devices each consist of four 2-input digital multiplexers with common select and strobe inputs. On the HD74HC157, when the strobe input is at logical “L” the four outputs assume the values as selected from the inputs. When the strobe input is at a logical “H” the outputs assume logical “L”. The HD74HC158 operates in the same manner, except that its outputs are inverted. Select decoding is done internally resulting in a single select input only.
