Features  
Description  
• Multifunction Capability  
The CD54HC4514, CD74HC4514, and CD74HC4515 are  
high-speed silicon gate devices consisting of a 4-bit strobed  
latch and a 4- to 16-line decoder. The selected output is  
enabled by a low on the enable input (E). A high on E inhibits  
selection of any output. Demultiplexing is accomplished by  
- Binary to 1-of-16 Decoder  
- 1-to-16 Line Demultiplexer  
• Fanout (Over Temperature Range)

using the E input as the data input and the select inputs (A0-

when these devices are cascaded.

• Wide Operating Temperature Range . . . -55 C to 125 C  
• Balanced Propagation Delay and Transition Times  
When Latch Enable (LE) is high the output follows changes  
in the inputs (see truth table). When LE is low the output is  
isolated from changes in the input and remains at the level  
(high for the 4514, low for the 4515) it had before the latches  
were enabled. These devices, enhanced versions of the  
equivalent CMOS types, can drive 10 LSTTL loads.
