Philips Semiconductors Product specification 4-to-16 line decoder/demultiplexer with input latches 74HC/HCT4514 The 74HC/HCT4514 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 outputs (Q0 to Q15) are mutually exclusive active HIGH. When LE is HIGH, the selected output is determined by the data on An.

Philips Semiconductors Product specification 4-to-16 line decoder/demultiplexer with input latches 74HC/HCT4514 DC CHARACTERISTICS FOR 74HCT For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”. Output capability: standard ICC category: MSI Note to HCT types The value of additional quiescent supply current (∆ICC) for a unit load of 1 is given in the family specifications. To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below.
