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

STATIC ELECTRICAL CHARACTERISTICS (continued)
Characteristics noted under conditions of 7.0 V ≤ VBAT ≤ 16 V, -40°C ≤ TA ≤ 125°C, SLEEP = 5.0 V unless otherwise noted. Typical
values reflect the parameter's approximate midpoint average value with VBAT = 13 V, TA = 25°C. All positive currents are into the
pin. All negative currents are out of the pin.
