The 16 inverting outputs (Q to Q ) are mutually exclusive active LOW. 0 15 I category: MSI CC When LE is HIGH, the selected output is determined by the data on A . When LE goes LOW, the last data present at n GENERAL DESCRIPTION A are stored in the latches and the outputs remain stable. n When E is LOW, the selected output, determined by the The 74HC/HCT4515 are high-speed Si-gate CMOS contents of the latch, is LOW. When E is HIGH, all outputs devices and are pin compatible with 4515 of the 4000B are HIGH. The enable input (E) does not affect the state of series. They are specified in compliance with JEDEC the latch. standard no. 7A. When the 4515 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 25 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 46 pF PD Notes 1.
