Additional Details:

The PT2243-S transmits address and data code when the transmit enable pin is activated. The address and data are set by configuring the corresponding pins to either a high or low logic level. This encoder is used in conjunction with compatible decoder ICs. It operates on a supply voltage range typically between 2.4V and 12V. The 'S' suffix likely indicates a specific configuration of the address and data pins. An external resistor connected to the OSC1 and OSC2 pins sets the oscillator frequency.
