Additional Details:

The PT2240-S IC encodes address and data information and modulates an RF carrier when the transmit enable pin is active. The address and data are programmed by setting pins to either a high or low logic level. The IC is intended to be paired with a corresponding decoder IC at the receiver end for seamless operation. The oscillator frequency is determined by an external resistor connected between OSC1 and OSC2 pins. The PT2240-S operates with a supply voltage range typically between 2.4V and 12V. The 'S' suffix typically indicates a specific configuration of address and data lines within the PT2240 series.
