33290
The 33290 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 33290 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 33290 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 33290 was principally designed for automotive
applications, it is suited for other serial communication applications.
It is parametrically specified over an ambient temperature range of
-40ºC ≤ TA ≤ 125ºC and 8.0 V ≤ VBB ≤ 18 V supply. The economical
SO-8 surface-mount plastic package makes the 33290 very cost
effective.

2. Device will survive double battery jump start conditions in typical applications for 10 minutes duration, but is not guaranteed to remain
within specified parametric limits during this duration.
3. ESD data available upon request.
4. ESD1 testing is performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 Ω), ESD2 testing is performed in
accordance with the Machine Model (CZAP = 200 pF, RZAP = 0 Ω).

Nonrepetitive clamping capability at 25°C.
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.
Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
