MAX3386EIPW

Overview

The MAX3386EIPW is a low-power RS-232 transceiver manufactured by Texas Instruments, designed for portable applications. It features three drivers and two receivers, supporting full-duplex communication at data rates up to 250 kb/s. The device operates on a single 3 V to 5.5 V supply with a typical quiescent current of 1 mA. It includes a shutdown mode to minimize power consumption. The component provides ±15 kV electrostatic discharge (ESD) protection on all lines using the IEC 1000-4-2 air-gap method. It is housed in a 20-pin TSSOP package and supports operation within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated ESD protection rated at ±15 kV on all RS-232 inputs and outputs.
• Low-power architecture with dedicated shutdown control pin for battery conservation.
• Single-supply operation compatible with 3 V and 5 V logic systems.
• High-speed transmission capability supporting data rates up to 250 kb/s.

Applications

• Portable personal digital assistants (PDAs)
• Cellular phones and mobile communication devices
• Battery-powered industrial instrumentation

Procurement Notes

Verify the specific suffix 'IPW' corresponds to the 20-TSSOP package variant when sourcing. Confirm RoHS compliance status as manufacturing processes evolve. Check for end-of-life notices or obsolescence warnings from Texas Instruments prior to finalizing procurement plans. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component for designs requiring robust ESD protection in space-constrained portable electronics. Compare against the TRS3386 series if extended temperature ranges or different packaging options are required. Verify that the 250 kb/s speed meets system requirements. Ensure the 20-TSSOP footprint matches the PCB layout constraints.

Part Context

This part belongs to the MAX3386 family of RS-232 transceivers originally developed by Maxim Integrated before its acquisition by Texas Instruments. The family focuses on low-voltage, low-power interfaces for mobile devices. The 'E' designation typically indicates enhanced ESD protection capabilities compared to standard variants.

Replacement Considerations

The TRS3386EIPWR is a parameter-equivalent replacement available from Texas Instruments. Both parts share similar electrical characteristics and pinouts. Verify package compatibility and ensure the replacement meets the specific ESD and temperature requirements of the original design.
