Quad 2-input multiplexer

Rev. 9 — 24 July 2020

Product data sheet

1. General description

The 74HC157; 74HCT157 is a quad 2-input multiplexer. The device features select (S) and enable

E inputs. A HIGH on S selects data source 1, a LOW data source 0. A HIGH on E forces all the

outputs (1Y to 4Y) LOW. Inputs include clamp diodes. This enables the use of current limiting

resistors to interface inputs to voltages in excess of V_CC

2. Features and benefits

•

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 74HC157: CMOS level

For 74HCT157: TTL level

•

Non-inverting data path

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

•

Multiple package options

Specified from -40 °C to +85 °C and from -40 °C to +125 °C
