74HCT4514PW,112

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HCT4514PW,112 is a 4-to-16 line decoder/demultiplexer with input latches. It features four binary weighted address inputs (A0 to A3), a latch enable input (LE), an enable input (E), and 16 outputs (Q0 to Q15). The device operates on a single supply voltage ranging from 4.5 V to 5.5 V. It decodes 4 binary-coded inputs into 16 mutually-exclusive outputs. When LE is HIGH, the selected output is determined by data on An; when LE goes LOW, the last data are stored in the latches. The enable input E does not affect the state of the latch.
