Technical Data

Class B Serial Transceiver

33390

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.
