Receiver for Point-to-Point Multiplex Systems
U6057B
Description
Local, low speed multiplex systems reduce the amount of
wires and connectors, save costs and weight and increase
the safety in automotive and industrial applications. The
U6057B is an ideal receiver for an 8-bit data word with
simple protocol of a fixed length. It checks the correct
data transmission and provides the data word in an 8-bit
shift register for a microcontroller.
