74HC154D

74HC154DThe 74HC154; 74HCT154 is a 4-to-16 line decoder/demultiplexer. It decodes four binary weighted address inputs (A0 to A3) tosixteen mutually exclusive outputs (Y0 to Y15). The device features two input enable (E0 and E1) inputs. A HIGH on either of theinput enables forces the outputs HIGH. The device can be used as a 1-to-16 demultiplexer by using one of the enable inputs as themultiplexed data input. When the other enable input is LOW the addressed output will follow the state of the applied data. Inputsinclude clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
