ISO K Line Serial Link Interface
IL33290
The IL33290 is a serial link bus interface device
designed to provide bidirectional 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 IL33290 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 overtemperature conditions.
The IL33290 derives its robustness to temperature
and voltage extremes by being built on a process,
incorporating CMOS logic, bipolar/MOS analog
circuitry, and DMOS power FETs. Although the IL33290 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°C ≤ TA ≤ 125°C and
8.0 V ≤ VBB ≤ 18 V supply. The economical SO-8 surface-mount plastic package makes
the IL33290 very cost effective.

Notes
15. ISO ramped from 0.8 VBB to 0.4 VBB, Monitor RX, Value of ISO voltage at which RX transitions to 0.3 VDD.
16. ISO ramped from 0.4 VBB to 0.8 VBB, Monitor RX, Value of ISO voltage at which RX transitions to 0.7 VDD.
17. Input Hysteresis, VHys(ISO) = VIH(ISO) - VIL(ISO).
18. ISO has internal current limiting.
