MAX213IDWG4

Drivers, Receivers, Transceivers Overview

The MAX213IDWG4 is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 5-V supply and includes internal charge pumps to generate voltages for RS-232 signal transmission. The device features four drivers and five receivers, supporting full-duplex communication with a data rate of 120 kb/s. It provides ±15-kV electrostatic discharge (ESD) protection on RS-232 lines. The component functions within a supply voltage range of 4.5 V to 5.5 V and draws 20 mA of operating current. It is housed in a 28-pin TSSOP package and operates between -40°C and +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for external capacitors larger than 0.1 µF.
• Provides robust ±15-kV ESD protection directly on the RS-232 transceiver lines.
• Includes a shutdown mode to significantly reduce power consumption during idle periods.

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable serial communication.
• Portable instrumentation and battery-powered devices utilizing RS-232 interfaces.
• Modem and communications equipment designs.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix IDWG4 against the manufacturer's official datasheet to confirm the tape-and-reel packaging variant and temperature grade. Ensure compatibility with existing PCB footprints for the 28-pin TSSOP package. Confirm that the component meets all required environmental standards for the intended deployment environment before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple RS-232 channels without external boost capacitors. It is suitable for applications needing high ESD immunity and low standby power via shutdown mode. Compare pinout and electrical specifications against legacy parts like the MAX211 or TRS213 if replacing existing designs.

Drivers, Receivers, Transceivers Part Context
