SN75LV4737ADBR

Drivers, Receivers, Transceivers Overview

The SN75LV4737ADBR is a low-voltage RS-232 transceiver from Texas Instruments, designed for single-supply operation. It integrates three drivers and five receivers to support standard RS-232 communication protocols. The device operates within a voltage range of 3.0 V to 3.6 V, with a typical supply current of 1 mA. It supports data rates up to 1 Mb/s and includes ESD protection rated at 15 kV. Packaged in an 8-pin SOIC (DB) format, it functions as a complete interface solution for serial communication applications requiring low power consumption and high noise immunity.

Drivers, Receivers, Transceivers Feature Summary

• Integrates three independent drivers and five independent receivers on a single chip
• Provides robust electrostatic discharge protection meeting IEC 61000-4-2 standards
• Operates efficiently from a single 3-V to 3.6-V power supply
• Supports data transmission speeds up to 1 megabit per second

Drivers, Receivers, Transceivers Applications

• Portable battery-powered equipment such as laptops and PDAs
• Industrial control systems requiring reliable serial communication
• Modems and other telecommunications interface devices

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DBR confirms the tape-and-reel packaging variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the operating temperature range aligns with your system requirements before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require full RS-232 functionality with minimal external components. It is suitable for space-constrained designs due to its compact package. Consider the 3-V to 3.6-V supply constraint during power budgeting. Verify that the 1-Mb/s speed meets your application's throughput needs compared to higher-speed alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75LV4737A series of low-voltage RS-232 transceivers. The series is characterized by its ability to operate from a single low-voltage supply while generating the necessary positive and negative voltages for RS-232 signaling internally. It serves as a drop-in replacement for traditional dual-supply RS-232 solutions in modern low-power electronics.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as the SN75LV4737ADB. Verify electrical parameters like supply voltage and data rate against alternative parts from other manufacturers to ensure functional equivalence in your specific circuit design.
