74HC154; 74HCT154

4-to-16 line decoder/demultiplexer

Rev. 9 — 19 August 2021

Product data sheet

1. General description

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.

2. Features and benefits
