UM3750 Datasheet | UMC Corporation

UN13750 Programmable Encoder/Decoder Single chip contains both Encoder and Decoder. 3V to 11 V operation. On chip oscillator uses non-critical RC ponents. Cross interference of recetver is virtually eliminated by circuitry which requires 4 valid words to be received, each within 64ms of the other. Schmitt Trigger input provides excellent noise immunity. Applications. alarm control system, security system cordless telephone, remote control. Interfaces with RF, ultrasonic, or infrared modulators I and demodulators General Description T h e U M 3 7 5 0 E n c o d e r / D e c o d e r is a CMOS/LSI digital code Transmitter-Receiver system. Working in the transmit (encoder) mode, the UM3750...
