THCS131_Rev.1.01_E THCS131 I/OSpreader General Description Features The THCS131 provides a function to serialize multiple parallel signals into single-ended serial line at least or to deserialize the data stream over single-ended serial line or single differential pair into multiple parallel signals. This small number of transmission line simplifies system configuration and reduces system cost including cable width, connector size and pins and PCB layout area. The THCS131 is offered in 8bit parallel IOs as host MPU interface. It can transfer 8bit independent parallel signals to remote side by only 1-line or 1-pair cable. Transmitter or receiver function can be selected by pin options. - No External Clock Required. -8bit Parallel IOs to MPU. - Single-ended/Differential Mode (noise tolerant) Selectable - AC Coupling Supported with Differential Mode - Transmission Status Error Indicator Supported (Line Cut Detection and Packet Error Detection) - Power supply : 3.0 to 5.5V - DIP 20-pin Package - EU RoHS Compliant Block Diagram THCS131 TXEN RXEN (Tx/Rx select) DATA<7:0> (Parallel IO) OSC IOP ION IO (Serial IO) MUX CTL0 CTL1 (IO control) SER & DES RSTN (reset input) FAULTN SIG (error flag output) (single-ended/differential select) Copyright©2014 THine Electronics, Inc. 1/10 THine Electronics, Inc.

When the protocol of received data is not correct or serial data more than 50usec (typ) is not received, FAULTN pin will be changed into low level. The received data is canceled when a FAULTN pin outputs Low. When normal serial data is received, a FAULTN pin outputs High in case of pulled up externally.
