Order this document by MC33290/D Advance Information ISO Serial Link Interface The MC33290 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 MC33290 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 over temperature conditions. The MC33290 derives it’s robustness to temperature and voltage extremes from being built on a SMARTMOS™ process, incorporating CMOS logic, bipolar/MOS analog circuitry, and DMOS power FETs. Though the MC33290 was principally designed for automotive applications, it is suited for other serial munication applications. It is parametrically specified over an ambient temperature range of - 40°C ≤ TA ≤ 125°C and 8.0 V ≤ VBat ≤ 18 V supply. The economical 8 pin DIP and SO- 8 surface mount plastic packages make the MC33290 very cost effective. - Designed to Operate Over Wide Supply Voltage of 8.0 to 18 V ISO SERIAL LINK INTERFACE SEMICONDUCTOR TECHNICAL DATA - - - - - - - - - - 8 1 Ambient Operating Temperature of - 40°C to 125°C Interfaces Directly to Standard CMOS Microprocessors ISO K Line Pin Protected Against Shorts to Ground Thermal Shutdown with Hysteresis Maximum Transmission Speeds in Excess of 50 k Baud ISO K Line Pin Capable of High Currents ISO K Line can be Driven with up to 10 n F of Parasitic Capacitance 8.0 k V ESD Protection Attainable with Few Additional ponents Standby Mode: No VBat Current Drain with VDD at 5.0 V Low Current Drain during Operation with VDD at 5.0 V P SUFFIX PLASTIC PACKAGE CASE 626 D SUFFIX PLASTIC PACKAGE CASE 751 (SO- 8) Typical Application Schematic On- Board Diagnostic Link +VBat D(1) +VDD MCU VCC 5.0 V 7 1.0 n F Dx SCIRx D SCITx D 5 8 6 CEN Rx Tx Gnd 3 ISO 4 27...
