Holtek Semiconductor HT12F
the HT12F device, although mentioned in this datasheet, has already been phased out and is presently no longer available. They are paired with Holtek¢s 212 series of encoders (refer to the encoder/decoder cross reference table). For proper operation, a pair of encoder/decoder with the same number of addresses and data format should be chosen.| Part No. | HT12F |
