ISO K Line Serial Link Interface
The 33660 is a serial link bus interface device designed to provide
bi-directional half-duplex communication interfacing in automotive
diagnostic applications. It is designed to interface between the
vehicle’s on-board microcontroller, and systems off-board the vehicle
via the special ISO K line. The 33660 is designed to meet the
Diagnostic Systems ISO9141 specification. The device’s K line bus
driver’s output is fully protected against bus shorts and over-
temperature conditions.
The 33660 derives its robustness to temperature and voltage
extremes by being built on a SMARTMOS process, incorporating
CMOS logic, bipolar/MOS analog circuitry, and DMOS power FETs.
Although the 33660 was principally designed for automotive
applications, it is suited for other serial communication applications. It
is parametrically specified over an ambient temperature range of
-40 ºC TA 125 ºC and 8.0 V VBB 18 V supply. The economical
SO-8 surface-mount plastic package makes the 33660 very cost
effective.
Features
• Operates over wide supply voltage of 8.0 to 18 V
• Operating temperature of -40 to 125 °C
• Interfaces directly to standard CMOS microprocessors
• ISO K line pin protected against shorts to battery
• Thermal shutdown with hysteresis
• ISO K line pin capable of high currents
• ISO K line can be driven with up to 10 nF of parasitic capacitance
• 8.0 kV ESD protection attainable with few additional components
• Standby mode: no VBAT current drain with VDD at 5.0 V
• Low current drain during operation with VDD at 5.0 V
