When E is LOW, the selected The HEF4514B is a 1-of-16 decoder/demultiplexer, having output, determined by the contents of the latch, is HIGH. four binary weighted address inputs (A to A ), a latch 0 3 At E HIGH, all outputs are LOW. The enable input (E) does enable input (EL), and an active LOW enable input (E). not affect the state of the latch.
