NXP Semiconductors 74F154
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.| Part No. | 74F154 |

FEATURES
● 16-line demultiplexing capability● Mutually exclusive outputs
● 2-input enable gate for strobing or expansion
DESCRIPTION
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. TYPICAL PROPAGATION DELAY 5.5 ns TYPICAL SUPPLY CURRENT (TOTAL) 26mA ORDERING INFORMATIONDESCRIPTION
