TH3122 K-Bus Transceiver

The TH3122 consists of a low drop voltage regulator 5V/100mA and a K-Bus transceiver. The transceiver is suitable for K-Bus systems conform to ISO 9141. The combination of voltage regulator and bus transceiver in combination with the monitoring functions make it possible to develop simple, but power.
