SX8743 (SX8733 - SX87440) Precision Diode Digital Temperature

The SX8733, SX8743 and SX8744 are digital temperature sensors with a 2-wire SMBus interface. It provides a lowcost solution to monitor the temperature of remote diodes as well as its own temperature with an on-chip PN junction sensor. Depending on the device version, 2, 3 or 4 programmable ports are.
