MAX3318EIPW

Overview

The MAX3318EIPW is a dual-driver, dual-receiver RS-232 transceiver manufactured by Texas Instruments. It operates from a single 2.25-V to 3-V supply and supports data rates up to 460 kbps. The device integrates a charge pump requiring only four 0.1-μF capacitors. It features ±15-kV ESD protection on RS-232 I/O pins per the IEC 61000-4-2 Air-Gap Discharge method. Supply current is 300 μA in normal operation and reduces to 1 μA in low-power standby mode with receivers active. The component is housed in a 20-pin TSSOP package.

Feature Summary

Integrated auto-power-down plus feature reduces supply current to 1 μA when drivers are inactive for approximately 30 seconds.
Proprietary low-dropout driver output stage enables RS-232-compatible operation from a 2.25-V to 3-V supply.
Flexible power management control via FORCEON and FORCEOFF inputs allows manual override of auto-power-down modes.

Applications

Battery-powered systems
PDAs
Cellular phones
Notebooks
Hand-held equipment

Procurement Notes

Verify the specific ordering suffix against the latest TI Package Option Addendum to confirm status and packaging. The MAX3318EIPW designation indicates an obsolete production status; ensure availability aligns with design requirements before finalizing procurement plans.

Selection Notes

Select this component for applications requiring low-voltage RS-232 communication with minimal external capacitance. Ensure the system supply voltage remains within the 2.25-V to 3-V range. Verify that the 20-pin TSSOP package dimensions fit the target PCB layout constraints.

Part Context

The MAX3318E series belongs to Texas Instruments' family of low-power RS-232 transceivers designed for portable electronics. This specific part number denotes the industrial temperature grade variant (-40°C to +85°C) packaged in a 20-pin Thin Shrink Small Outline Package (TSSOP).
