The 16 outputs (Q to Q ) are mutually exclusive active HIGH. When LE 0 15 I category: MSI CC is HIGH, the selected output is determined by the data on A . When LE goes LOW, the last data present at A are n n GENERAL DESCRIPTION stored in the latches and the outputs remain stable. When E is LOW, the selected output, determined by the contents The 74HC/HCT4514 are high-speed Si-gate CMOS of the latch, is HIGH. At E HIGH, all outputs are LOW. The devices and are pin compatible with 4514 of the 4000B enable input (E) does not affect the state of the latch. series. They are specified in compliance with JEDEC standard no. 7A. When the 4514 is used as a demultiplexer, E is the data input and A to A are the address inputs. 0 3 QUICK REFERENCE DATA GND = 0 V; T =25 C; t =t = 6 ns amb r f TYPICAL SYMBOL PARAMETER CONDITIONS UNIT HC HCT t / t propagation delay A to Q C = 15 pF; V =5 V 23 26 ns PHL PLH n n L CC C input capacitance 3.5 3.5 pF I C power dissipation capacitance per package notes 1 and 2 44 45 pF PD Notes 1.
