Compatible with PCA82C250 DeviceNet, SDS, ISO11898 Compatible High Speed, 1Mbps Differential Transmit Receive from Controller Least Nodes Connected 100V Transient Protection Transmit Output Supply Cross Wire Protection CANH CANL Loading When Powered Down Operates over -40°C +125°C Unitrode DeviceNet ID#107
PRELIMINARY DESCRIPTION
UC5350 Control Area Network Transceiver designed industrial applications employing serial communications physical layer 11898 standard. device high speed transceiver designed 1Mbps. Especially designed hostile environments, this device features cross wire, loss ground, over voltage, over temperature protections well wide common mode range. transceiver interfaces single ended controller with differential found industrial automotive applications. operates over +12V common mode range will withstand common mode transients -25V +18V well Schaffner tests. Performance features include high differential input impedance, symmetrical differential signal driver very propogation delay that improves bandwidth length reducing reflection distortion. transceiver operates over wide temperature range, -40°C +125°C available 8-pin SOIC Dual-in-Line packages.
