Class B Serial Transceiver The 33390 is a serial transceiver designed to provide bi-directional half-duplex communication meeting the automotive SAE Standard J- 1850 Class B Data Communication Network Interface specification. It is designed to interface directly to on-board vehicle microcontrollers and serves to transmit and receive data on a single-wire bus at data rates of 10.4 kbps using Variable Pulse Width Modulation (VPWM). The 33390 operates directly from a vehicle's 12 V battery system and functions in a logic fashion as an I/O interface between the microcontroller's 5.0 V CMOS logic level swings and the required 0 V to 7.0 V waveshaped signal swings of the bus. The bus output driver is short circuit current limited. Features • Designed for SAE J-1850 Class B Data Rates • Full Operational Bus Dynamics Over a Supply Voltage of 9.0 to 16 V • Ambient Operating Temperature of -40 °C to 125°C • Interfaces Directly to Standard 5.0 V CMOS Microcontroller • BUS Pin Protected Against Shorts to Battery and Ground • Thermal Shutdown with Hysteresis • Voltage Waveshaping of Bus Output Driver • 40 V Max VBAT Capability • Pb-Free Packaging Designated by Suffix Code EF Figure 1. 33390 Simplified Application Diagram J-1850 SERIAL TRANSCEIVER D SUFFIX EF SUFFIX (PB-FREE) 98ASB42564B 8-LEAD SOICN 33390 ORDERING INFORMATION Device Temperature Range (TA) Package MC33390D/DR2 -40°C to 125°C 8 SOICN MCZ33390EF/R2 33390 Primary Node Secondary Nodes MCU VPWR +VBAT SLEEP TX RX 4X/Loop GND BUS LOAD |
