MCZ33390EFR2

The MCZ33390EFR2 from NXP Semiconductors is a Class B serial transceiver engineered for automotive SAE J1850 Class B data communication networks. This device provides bi-directional, half-duplex communication on a single-wire bus, supporting data rates up to 10.4 kbps using Variable Pulse Width Modulation (VPWM).

Designed for direct interface with vehicle microcontrollers, it operates from a 12V battery system, functioning as an I/O interface between 5.0V CMOS logic and the bus's 0V to 7.0V signal swings. Key electrical specifications include a supply voltage range of 9V to 16V, a data rate of 10.4Kbps, and receiver hysteresis of 200mV. The transceiver is built to withstand harsh automotive environments, with an operating temperature range of -40°C to 125°C.

The MCZ33390EFR2 is housed in an 8-SOIC surface-mount package, measuring 0.154 inches (3.90mm) in width. The BUS pin is protected against shorts to battery and ground, and the device features thermal shutdown with hysteresis. It is designated as Pb-Free packaging by the suffix code EF.

This transceiver is suitable for applications requiring reliable serial communication within automotive systems, such as engine control modules or body electronics, where adherence to the SAE J1850 standard is necessary.
