74HC157; 74HCT157

Quad 2-input multiplexer

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.

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
