XL33290 SOP8 ISO K Line Serial Link Interface The 33290 is a serial link bus interface device designed to provide bi-directional half-duplex munication 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 munication 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.
