74HC154; 74HCT154

4-to-16 line decoder/demultiplexer

The 74HC154; 74HCT154 is a 4-to-16 line decoder/demultiplexer. It decodes four binary weighted address inputs (A0 to A3) to sixteen mutually exclusive outputs (Y0 to Y15). The device features two input enable (E0 and E1) inputs. A HIGH on either of the input enables forces the outputs HIGH. The device can be used as a 1-to-16 demultiplexer by using one of the enable inputs as the multiplexed data input. When the other enable input is LOW the addressed output will follow the state of the applied data. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Features and benefits

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
  • 16-line demultiplexing capability
  • Decodes 4 binary-coded inputs into 16 mutually-exclusive outputs
  • Input levels:
    • For 74HC154: CMOS level
    • For 74HCT154: TTL level
  • Complies with JEDEC standards:
    • JESD8C (2.7 V to 3.6 V)
    • JESD7A (2.0 V to 6.0 V)
  • ESD protection:
