MAX3386EIPWR

Overview

The MAX3386EIPWR is a low-power RS-232 transceiver manufactured by Texas Instruments, housed in a 20-pin TSSOP package. It supports full-duplex communication with three drivers and two receivers, operating at data rates up to 250 kb/s. The device functions within a supply voltage range of 3 V to 5.5 V, drawing only 1 mA of operating current. It features integrated shutdown capabilities for power conservation and provides 15 kV ESD protection on all inputs and outputs. The component is rated for commercial temperatures between 0°C and +70°C.

Feature Summary

• Integrated 15 kV electrostatic discharge protection on all RS-232 pins
• Low quiescent current consumption with dedicated shutdown mode
• Single 3 V or 5 V power supply operation
• Full compliance with EIA/TIA-232-F and ITU-T V.28/V.24 standards

Applications

• Portable computing devices requiring serial connectivity
• Industrial control systems with RS-232 interfaces
• Communication equipment utilizing standard serial protocols

Procurement Notes

Verify the specific suffix IPWR against official Texas Instruments documentation to confirm the tape-and-reel packaging format and temperature grade. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Ensure the source document explicitly identifies the part as active or obsolete before procurement planning.

Selection Notes

Select this component when a 20-pin surface-mount solution is required for 3V or 5V RS-232 applications. The MAX3386EIPWR offers a balance of moderate data rates and high ESD robustness. Compare pinout compatibility with existing designs, as it serves as a functional equivalent to other 3/2 driver receiver transceivers in the same package family.

Part Context

This part belongs to the MAX3386E series of low-power RS-232 transceivers designed for portable electronics. It shares architectural similarities with the TRS3386E line but is distinguished by its specific commercial temperature rating and packaging configuration. The device represents a transition from older lead-based Maxim products to Texas Instruments' manufacturing standards.

Replacement Considerations

The TRS3386EIPWR is a parameter-equivalent alternative available from Texas Instruments. Verify pin-to-pin compatibility and electrical specifications before substitution. Other legacy parts like the MAX3223 may require schematic modifications due to different driver/receiver counts.
