4- to 16-Line Decoder/Demultiplexer with Two Enables and Active-Low Outputs
When the active-Low enable inputs G1 and G2 of the X74_154 decoder/demultiplexer are Low, one of 16 active-Low outputs, Y15 – Y0, is selected under the control of four binary address inputs A, B, C, and D. The non-selected inputs are High. Also, when either input G1 or G2 is High, all outputs are High. The X74_154 can be used as a 16-to-1 demultiplexer by tying the data input to one of the G inputs and tying the other G input Low.
