THCS132_Rev.1.01_E
THCS132
I/OSpreader
General Description
The THCS132 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 THCS132 is offered in 8bit/16bit parallel
IOs as host MPU interface. It can transfer 16bit
independent parallel signals to remote side by
only 1-line or 1-pair cable. Also, the THCS132
set as master device can control plural slave
devices by transmitting and receiving data that is
designated as a device address.
Transmitter, receiver or transceiver function can
be selected by pin options.
