Decoder/demultiplexer
FEA TURES
•16-line demultiplexing capability
•Mutually exclusive outputs
•2-input enable gate for strobing or expansion
DESCRIPTION
The 74F154 decoder accepts four active High binary address inputs
and provides 16 mutually exclusive active Low outputs. The 2-input
Enable (E
the normal decoding “glitches” on the outputs, or it can be used for
expansion of the decoder. The enable gate has two AND’ed inputs
which must be Low to enable the outputs.
The 74F154 can be used as 1-of-16 demultiplexer by using one of
the Enable inputs as the multiplexed data input. When the other
Enable is Low, the addressed output will follow the state of the
applied data.
0, E1) gate can be used to strobe the decoder to eliminate

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
