33390
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.
