THCS131
I/OSpreader
General Description
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.
Features
- 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

Output is controlled by signal of output enable (CTL0,CTL1).
A pull-up state is continued until it sets signal of output
enable to LOW.
