UM3750 Datasheet PDF – Programmable Encoder / Decoder

Part Number : UM3750

Function : Programmable Encoder / Decoder

Package : DIP 18 Pin

Manufacturers : UMC


UM3750 datasheet

Description :

The UM3750 Encoder / Decoder 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.


Pinouts :
