Notes
1. An external series diode must be used to provide reverse battery protection of the device.
2. SLEEP, TX, RX, and 4X/LOOP are normally connected to a microcontroller.
3. ESD1 testing is performed in accordance with the Human Body Model (CZAP=100 pF, RZAP=1500 ).
4. ESD2 testing is performed in accordance with the Machine Model (CZAP=200 pF, RZAP=0 ).




Description

The 33390 is a serial transceiver designed to provide bi-directional halfduplex communication meeting the automotive SAE Standard J-1850 Class B Data Communication Network Interface specification.33390 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.
