The receiving half of a 315/433 MHz remote-control pair: it listens to the coded stream from a PT2262 encoder and, when the address bits match, pulls its data outputs high and raises the VT (valid transmission) pin. This is the M4 version, so it has eight address pins and four momentary outputs - each output is high only while its button is held. Runs on 4 V to 15 V, sets its oscillator with a single resistor, and comes in an 18-pin DIP.
Key features
- Pairs with the PT2262 encoder
- M4 version: 8 address pins, 4 data outputs
- Momentary outputs - high only while the key is pressed
- VT pin flags a valid, address-matched transmission
- Operating voltage 4 V to 15 V
- Oscillator set by one external resistor
- 18-pin DIP
