Technical Data
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.
