MAX3386ECPW

Overview

The MAX3386ECPW is a low-power RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex communication. It integrates three drivers and two receivers within a single TSSOP-20 package. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It supports data rates up to 250 kb/s and includes an integrated shutdown mode to minimize power consumption during idle periods. The component provides robust protection against electrostatic discharge, rated at 15 kV according to the Human Body Model specification.

Feature Summary

• Integrates three independent drivers and two receivers for full-duplex RS-232 communication in a compact surface-mount package.
• Features a dedicated shutdown pin that significantly reduces supply current, enabling efficient power management in battery-operated systems.
• Provides high-level electrostatic discharge protection rated at 15 kV, ensuring signal integrity and device reliability in harsh environments.

Applications

• Portable equipment requiring low-power serial communication interfaces
• Battery-powered handheld devices and mobile terminals
• Industrial control systems utilizing RS-232 protocols

Procurement Notes

Verify the specific suffix 'CPW' to confirm the commercial temperature range (0°C to +70°C) and TSSOP-20 packaging. Confirm RoHS compliance status through official documentation as specifications may vary by production batch. Ensure the source is an authorized distributor to guarantee authenticity and traceability of the semiconductor components.

Selection Notes

Select this component when a full-duplex RS-232 interface is required with minimal power consumption. The 3-driver/2-receiver configuration suits applications needing multiple transmit lines but fewer receive lines. Compare against the TRS3386 series if an extended industrial temperature range (-40°C to +85°C) is necessary for the target environment.

Part Context

This part belongs to the MAX3386 family of low-power RS-232 transceivers. It shares functional similarities with the TRS3386 series but differs in temperature rating and packaging options. The E suffix indicates enhanced performance characteristics, while CPW denotes the specific commercial grade and TSSOP-20 form factor used in space-constrained designs.

Replacement Considerations

The TRS3386EIPWR is a functionally equivalent alternative offering an extended industrial temperature range. Verify pin compatibility and thermal requirements before substitution. Other compatible parts include variants from the MAX3232 or MAX3243 families, though driver/receiver counts may differ.
