Decoder/demultiplexer
Product specification
74F154
FEATURES
• 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 (E0, E1) gate can be used to strobe the decoder to eliminate
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.
