Philips Semiconductors Product specification 4-to-16 line decoder/demultiplexer with input latches; inverting 74HC/HCT4515 The 74HC/HCT4515 are 4-to-16 line decoders/demultiplexers having four binary weighted address inputs (A0 to A3) with latches, a latch enable input (LE), and an active LOW enable input (E). The 16 inverting outputs (Q0 to Q15) are mutually exclusive active LOW. When LE is HIGH, the selected output is determined by the data on An.
