UM3750 Datasheet (UMC Corporation) - Programmable Encoder/Decoder

UM3750, Programmable Encoder/Decoder

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 will sequentially encode and transmit 12 bits of input.

Each of the 12 bits may be 1 or 0 to allow 4096 different codes.

In the receive (decoder

UN13750 Programmable Encoder/Decoder Single chip contains both Encoder and Decoder.

3V to 11 V operation.

On chip oscillator uses non-critical RC components.

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 modulat
