MCZ33790EG

Specialized Overview

The MCZ33790EG is a dual-channel Distributed System Interface (DSI) physical layer interface device designed for automotive and industrial applications. It supports bidirectional communication between master and slave ICs using SMARTMOS technology. The device operates with a logic supply voltage of 4.75 V to 5.25 V and a bus supply voltage ranging from 8.0 V to 25.0 V. It accommodates an operating ambient temperature range of -40 °C to +85 °C. The component features two independent DSI-compatible buses, supporting data rates up to 150 kbps. It includes internal pull-ups and pull-downs, on-board charge pump functionality, and provides 2.0 kV ESD capability.

Specialized Procurement Notes

Verify the datasheet revision history regarding part number availability. The document indicates that the MCZ33790EG/R2 variant was removed in Revision 12.0 and replaced by the MC33790HEG/R2. Confirm the specific ordering suffix required for procurement to ensure compatibility with existing inventory or design specifications.

Specialized Selection Notes

Select this component when a dual-channel DSI physical interface is required for distributed system architectures. Ensure the application environment stays within the specified -40 °C to +85 °C operating temperature range. Verify that the bus supply voltage requirements align with the 8.0 V to 25.0 V input specification for proper idle level generation.

Specialized Part Context

This device belongs to the Freescale Semiconductor analog integrated circuit family, specifically designed as a physical layer interface for the Distributed System Interface (DSI) bus. It utilizes SMARTMOS technology to provide robust signal conditioning and protection for automotive and industrial communication networks.

Specialized Replacement Considerations

Revision 12.0 of the datasheet explicitly states that the MCZ33790EG/R2 was deleted and replaced by the MC33790HEG/R2. Verify if the HE suffix variant serves as the direct replacement for the EG suffix version.
