Document Number: MC33660 NXP Semiconductors Rev 6.0, 7/2016 Technical Data ISO K line serial link interface 33660 The 33660 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 vehicles on-board microcontroller, and systems off-board the vehicle via the special ISO K line. The 33660 is designed ISO9141 PHYSICAL INTERFACE to meet the Diagnostic Systems ISO9141 specification. The devices K line bus drivers output is fully protected against bus shorts and over-temperature conditions. The 33660 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 33660 was principally designed for automotive applications, it is suited for other serial communication applications. It is parametrically specified over an ambient temperature range of -40 C T 125 C and 8.0 V V 18 V supply. The economical SO-8 A BB EF SUFFIX (PB-FREE) surface-mount plastic package makes the 33660 very cost effective. 98ASB42564B 8-PIN SOICN Features Operates over a wide supply voltage of 8.0 V to 18 V Operating temperature of -40 C to 125 C Applications Interfaces directly to standard CMOS microprocessors Farm equipment ISO K line pin protected against shorts to battery Automotive systems Thermal shutdown with hysteresis Industrial equipment ISO K line pin capable of high currents Robotic equipment ISO K line can be driven with up to 10 nF of parasitic capacitance Applications where module-to-module 8.0 kV ESD protection attainable with few additional components communications are required Standby mode: no V current drain with V at 5.0 V BAT DD Marine and aircraft networks Low current drain during operation with V at 5.0 V DD +V BAT V DD 33660 VDD VDD VBB MCU ISO K-LINE ISO Dx CEN SCIRxD RX TXD SCITxD TX GND RXD Figure 1. 33660 simplified application diagram 2016 NXP B.V.1 Orderable parts Table 1.
