74HC157; 74HCT157
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 VCC.
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
