Overview
The STG3384DTR is a bus transceiver manufactured by STMicroelectronics, featuring two drivers and two receivers. It operates within a supply voltage range of 6 V to 36 V and supports data transmission rates up to 25 Mbps. The device functions reliably across an operating temperature range from -40°C to +85°C. It is housed in an SO-18 surface-mount package and utilizes SMD/SMT installation methods.
Feature Summary
- Provides differential line transmission and reception capabilities for robust signal integrity
- Supports high-speed data communication with specified maximum bit rates
- Operates effectively under wide industrial voltage and temperature conditions
Applications
- Industrial fieldbus networks requiring reliable long-distance communication
- Automotive electronic control units utilizing standardized bus protocols
- Factory automation systems connecting sensors and actuators via serial interfaces
Procurement Notes
Verify the specific suffix 'DTR' against official manufacturer documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure compatibility with existing PCB footprints for the SO-18 package before procurement. Confirm end-of-life status or obsolescence notices through authorized distributors to mitigate supply chain risks for long-term production cycles.
Selection Notes
Select this component when designing systems requiring differential signaling over moderate distances with high noise immunity. Verify that the required data rate does not exceed 25 Mbps and that the system power supply aligns with the 6 V to 36 V operational window. Consider thermal management requirements for the SO-18 package if multiple units are densely packed on the board.
Part Context
This part belongs to the ST3384 family of bus transceivers designed for RS-485 and RS-422 applications. The series is characterized by its ability to handle harsh electrical environments common in industrial settings. The STG3384 variant typically denotes specific pinout or feature configurations within the broader product line, ensuring backward compatibility with standard interface designs.
Replacement Considerations
Cross-reference with other RS-485/RS-422 transceivers offering similar 2-driver/2-receiver architectures. Verify pin-to-pin compatibility and electrical parameter alignment, specifically regarding supply voltage ranges and data rates, before substituting with alternative manufacturers' components.
