IL33290D
MICROCIRCUIT ISO of K Line INTERFACE
DESCRIPTION
IL33290D – microcircuit of the serial interface, intended for ensuring the dual direction semi-
duplex connection in the automotive diagnostic applications. The microcircuit is designed to ensure
communication between the vehicle-borne microcontroller of the transport means and the external
systems via the special line ISO K. The microcircuit IL33290D is designed in compliance with
Specification of the diagnostic systems ISO9141. The microcircuit output, controlling line K, is
protected from short circuit and temperature overshoot.
