74HC154; 74HCT154
4-to-16 line decoder/demultiplexer
Rev. 7 — 29 February 2016
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
