Ht12d. Vt can be used as a momentary data output. The primary function of ht12d is to decode the 12 bit that is received by the input pin.
The ic is should be powered by 5v pin 18 and the ground pin pin 9 is grounded.

L stands for latch type data output. In this decoder only 4 bits are data the remaining part is the address. Data vt oscillator trigger package part no. Since the ic comes with an in built oscillator it is very easy to make this ic work.
