description
The UC5350 control area network (CAN) transceiver is designed for industrial applications employing the CAN
serial communications physical layer per ISO 11898 standard. The device is a high-speed transceiver designed
for use up to 1 Mbps. Especially designed for hostile environments, this device features cross wire, loss of
ground, overvoltage, and overtemperature protections as well as a wide common-mode range.
The transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial and
automotive applications. It operates over the 7-V to 12-V common-mode range of the bus and will withstand
common-mode transients of 25 V to 18 V as well as Schaffner tests. Performance features include high
differential-input impedance, 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 85
C and is available in 8-pin SOIC and
dual-in-line packages.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
Currents are positive into, negative out of the specified terminal. Consult Packaging Section of the Interface Products Data Book (TI Literature
Number SLUU002) for thermal limitations and considerations of packages.
