SKU MC33290D

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 -40C < TA < 125C and 8.0 V < VBB < 18 V supply. The
economical SO-8 surface-mount plastic package makes the 33290 very cost
