DESCRIPTION
The UC5350 Control Area Network Transceiver is designed for industrial
applications employing the CAN serial communications physical layer
per ISO 11898 standard. The device is a high speed transceiver de-
signed for use up to 1Mbps. Especially designed for hostile environ-
ments, this device features cross wire, loss of ground, over voltage, and
over temperature protections well as a wide common mode range.
The transceiver interfaces the single ended CAN controller with the dif-
ferential CAN bus found in industrial and automotive applications. It op-
erates over the –7V to +12V common mode range of the bus and will
withstand common mode transients of –25V to +18V as well as Schaff-
ner tests. Performance features include high differential input imped-
ance, a symmetrical differential signal driver and very low propogation
delay that improves bus bandwidth and length by reducing reflection and
distortion.
The transceiver operates over a wide temperature range, –40°C to
+125°C and is available in 8-pin SOIC and Dual-in-Line packages.
