HEF4515B - NXP

HEF4515B 1-of-16 decoder/demultiplexer with input latches

The HEF4515B is a 1-of-16 decoder/demultiplexer, having four binary weighted address inputs (A0 to A3), a latch enable input (EL), and an active LOW enable input (E). The 16 outputs (O0 to O15) are mutually exclusive active LOW. When EL is HIGH, the selected output is determined by the data on An. When EL goes LOW, the last data HEF4515B MSI present at An .

Features

e input (E) does not affect the state of the latch. When the HEF4515B is used as a demultiplexer, E is the data input and A0 to A3 are the address inputs. Fig.1 Functional diagram.
