MAX202IPW

Drivers, Receivers, Transceivers Overview

The MAX202IPW is a dual RS-232 line driver and receiver manufactured by Texas Instruments, designed for single-supply operation. It integrates two charge pumps to generate the required ±10V levels from a single +5V supply, eliminating the need for external negative voltage sources. The device features two drivers and two receivers, supporting full-duplex communication at data rates up to 120 kb/s. It operates within a supply voltage range of 4.5V to 5.5V and draws a typical operating current of 15 mA. The component is housed in a 16-pin TSSOP package and provides ±15 kV electrostatic discharge (ESD) protection on all pins.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge pumps to convert a single +5V supply into the ±10V output levels required for RS-232 signaling.
• Provides robust ±15 kV ESD protection on all input and output pins, including ground, ensuring signal integrity in harsh environments.
• Supports full-duplex asynchronous communication with independent drivers and receivers for reliable data transmission.

Drivers, Receivers, Transceivers Applications

• Providing electrical interface between asynchronous communication controllers and serial port connectors.
• Connecting personal computers to peripheral devices such as modems, printers, and industrial instruments.
• Enabling serial communication in battery-powered systems where generating negative voltages is impractical.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix IPW to confirm the TSSOP-16 package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for end-of-life notices or obsolescence warnings, as availability may be limited compared to newer revisions. Ensure ordering quantities align with tube packaging constraints if applicable.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX202IPW when a 16-pin surface-mount solution is required for dual-channel RS-232 communication. Choose this variant over SOIC packages if board space constraints favor the thinner TSSOP profile. Verify that the application requires the industrial temperature range rather than the commercial range offered by other suffixes. Ensure the design can accommodate the four small external capacitors needed for the internal charge pump circuitry.

Drivers, Receivers, Transceivers Part Context

The MAX202 belongs to the broader MAX202 family of RS-232 transceivers from Texas Instruments. This series is characterized by its ability to operate from a single 5V supply using internal charge pumps. The IPW suffix specifically denotes the industrial temperature range and the Thin Shrink Small Outline Package (TSSOP), distinguishing it from commercial variants like the CD or ID series which may offer different thermal performance or physical footprints.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the MAX202IDWR and MAX202IDR, which share identical electrical specifications but utilize an SOIC-16 package instead of TSSOP. Other family members such as the MAX202CD or MAX202CPW offer similar functionality but differ in temperature rating or package type. Verify that any replacement maintains the same 120 kb/s data rate and ±15 kV ESD protection capabilities.
