HT12D/HT12F — 2^12 Series Of Decoders

VT Oscillator Trigger Type Low power and high noise immunity CMOS. The HT12D on the other hand provides 4 latch type data pins whose data remain unchanged until new data are received. Synchronous operation More information. These are stress ratings only. It is identical More information. The outputs are fully buffered for the highest noise More information.

Of this series the HT12D is arranged to provide 8 address bits and 4 data bits and HT12F is used to decode 12 bits of address information.

Two regulated current ports are designed More information. On-chip address and data latches Self-timed More information. They are paired with. This will last unless the address code is incorrect or no signal is received. The VT pin also goes high to indicate a valid transmission. The open-collector outputs require external pull-up. Flowchart The oscillator is disabled in the standby state and activated when a logic high signal applies to the DIN pin.
