It is paired with a compatible 212-series encoder; the pair must use the same number of address bits and the same data format.<\/p>\n<p>The HT-12D converts serial input into parallel outputs. It compares the received serial address with its local address three times continuously. The source says data is decoded when no error or unmatched code is found; a valid transmission is indicated by HIGH on VT. The 12-bit word comprises 8 address bits and 4 data bits. In the 4-bit latch-type output, data remains unchanged until new data is received.<\/p>\n<p><a href=\"https:\/\/www.microplanet.ma\/en\/produit\/ht-12e-encoder-ic-remote-control-systems\/\">See the HT-12E encoder listing<\/a>.<\/p>\n<p><a href=\"https:\/\/www.microplanet.ma\/wp-content\/uploads\/2019\/02\/ht-12e-ht-12d.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8159\" src=\"https:\/\/www.microplanet.ma\/wp-content\/uploads\/2019\/02\/ht-12e-ht-12d-1000x752.png\" alt=\"\" width=\"590\" height=\"444\" srcset=\"https:\/\/www.microplanet.ma\/wp-content\/uploads\/2019\/02\/ht-12e-ht-12d-1000x752.png 1000w, https:\/\/www.microplanet.ma\/wp-content\/uploads\/2019\/02\/ht-12e-ht-12d-180x135.png 180w, https:\/\/www.microplanet.ma\/wp-content\/uploads\/2019\/02\/ht-12e-ht-12d-768x577.png 768w, https:\/\/www.microplanet.ma\/wp-content\/uploads\/2019\/02\/ht-12e-ht-12d-1536x1155.png 1536w, https:\/\/www.microplanet.ma\/wp-content\/uploads\/2019\/02\/ht-12e-ht-12d.png 1620w\" sizes=\"auto, (max-width: 590px) 100vw, 590px\" \/><\/a><\/p>\n<h4>Pin functions<\/h4>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"0\">\n<thead>\n<tr>\n<th>Pin<\/th>\n<th>Function<\/th>\n<th>Name<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1\u20138<\/td>\n<td>Eight address inputs<\/td>\n<td>A0\u2013A7<\/td>\n<\/tr>\n<tr>\n<td>9<\/td>\n<td>Ground (0V)<\/td>\n<td>GND<\/td>\n<\/tr>\n<tr>\n<td>10\u201313<\/td>\n<td>Four data\/address outputs<\/td>\n<td>D0\u2013D3<\/td>\n<\/tr>\n<tr>\n<td>14<\/td>\n<td>Serial data input<\/td>\n<td>Input<\/td>\n<\/tr>\n<tr>\n<td>15<\/td>\n<td>Oscillator output<\/td>\n<td>OSC2<\/td>\n<\/tr>\n<tr>\n<td>16<\/td>\n<td>Oscillator input<\/td>\n<td>OSC1<\/td>\n<\/tr>\n<tr>\n<td>17<\/td>\n<td>Valid transmission, active high<\/td>\n<td>VT<\/td>\n<\/tr>\n<tr>\n<td>18<\/td>\n<td>Supply; table lists 5V (2.4\u201312V)<\/td>\n<td>VCC<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The supply entry in the source is ambiguous.
