74HC151; 74HCT151

8-input multiplexer

The 74HC151; 74HCT151 is an 8-bit multiplexer with eight binary inputs (I0 to I7), three select inputs (S0 to S2) and an enable input (E). One of the eight binary inputs is selected by the select inputs and routed to the complementary outputs (Y and Y). A HIGH on E forces the output Y LOW and output Y HIGH. Inputs also include clamp diodes that enable 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

  • Input levels:

    • For 74HC151: CMOS level

    • For 74HCT151: TTL level

  • Non-inverting data path

  • Complies with JEDEC standards

    • JESD8C (2.7 V to 3.6 V)

    • JESD7A (2.0 V to 6.0 V)

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

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