DESCRIPTION  
The M74HC4514 is an high speed CMOS 4 LINE  
TO 16 LINE SEGMENT DECODER WITH  
LATCHED INPUTS fabricated with silicon gate  
available. The data applied to the data inputs are  
transferred to the Q outputs of latches when the  
strobe input is held high. When the strobe input is  
taken low, the information data applied to the data  
input at a time is retained at the output of the  
latches.  
All inputs are equipped with protection circuits  
against static discharge and transient excess  
voltage.  
2
C MOS technology.  
A binary code stored in the four input latches (A to  
D) provides a high level at the selected one of  
sixteen outputs excluding the other fifteen outputs,  
when the inhibit input (INHIBIT) is held low. When  
the inhibit input (INHIBIT) is held high, all outputs  
are kept low level, while the latch function is
