Enhanced Class B Serial
Transceiver
33990
The 33990 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 33990 operates directly from a vehicle's 12 V battery system and
functions in a true 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 V
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
• Internally Reverse Battery Protected
• 40 V Max VBAT Capability
• Pb-Free Packaging Designated by Suffix Code EF

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 ).
5. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
6. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL),
Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e.
MC33xxxD enter 33xxx), and review parametrics.
