The TMS3637 is a versatile 3-V to 6-V remote control transmitter/receiver in a small package that requires no external dual-in-line package (DIP) switches on the system circuit board. The device can be easily set for one of many transmit/receive configurations using configuration codes along with the desired security code, both of which are user programmable. When used as a transmitter, the device encodes the stored security code, transmits it to the remote receiver using any transmission media such as direct wiring, infrared, or radio frequency.
