DESCRIPTION

The 74HC4514 andthe 74HC4515 are high speed
CMOS 4-LINE TO 16-LINE DECODERS WITH
LATCHED INPUTS fabricated in silicon gate
C2MOS technology. They have the same high
speed performance of LSTTL combined with true
CMOS low powerconsumption.

A binary code stored in the four input latches (A to
D) provides a high level (HC4514) or a low level
(HC4515) at the selectedone ofsixteenoutputs ex­cluding the other fifteen outputs, when the inhibit
input(INHIBIT) is held low. When theinhibit input is
heldhigh, all outputsare keptlowlevel (HC4514) or
highlevel(HC4515), whilethelatchfunctionisavail­able.The data applied to the datainputs are trans­fered to the Q outputs of latches when the strobe
input is held high. When the strobe input is taken
low,the information dataappliedto thedata input at
a time is retained at theoutput of thelatches. All in­puts are equipped with protection circuits against
staticdischarge and transient excessvoltage.
