MAX202IPWRE4

Drivers, Receivers, Transceivers Overview

The MAX202IPWRE4 is a dual RS-232 line driver and receiver manufactured by Texas Instruments, designed for single-supply operation. It operates within a voltage range of 4.5 V to 5.5 V, typically utilizing a 5 V supply. The device supports data rates up to 120 kb/s and features full-duplex communication with two drivers and two receivers. It is housed in a TSSOP-16 surface-mount package and functions across an industrial temperature range from -40°C to +85°C. The component draws a typical operating supply current of 15 mA and includes integrated ESD protection rated at 15 kV.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for external negative voltage supplies.
• Provides robust electrostatic discharge protection on all pins to safeguard connected equipment.
• Supports standard RS-232 signaling protocols for reliable serial data transmission.

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring serial communication interfaces.
• Portable battery-powered devices due to low power consumption characteristics.
• Modem and fax machine internal communication links.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RE4 indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the TSSOP-16 package dimensions match the target PCB footprint. Ensure the industrial temperature grade meets environmental requirements. Check for obsolescence notices or lifecycle changes directly from Texas Instruments documentation before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 transceiver is required for space-constrained designs. The TSSOP-16 package offers a compact solution compared to larger DIP alternatives. Consider the 120 kb/s speed limit for applications not requiring high-speed data transfer. Verify that the 5 V single-supply architecture aligns with the system power budget and ground reference levels.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202 family of RS-232 transceivers from Texas Instruments. The IPW suffix denotes the TSSOP-16 package variant, while the RE4 suffix typically signifies environmental compliance attributes such as RoHS adherence. It serves as a direct replacement for older legacy RS-232 interface chips in modern embedded systems.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the MAX202IDWR and MAX202IPWR. Alternative series like the TRS202 may offer similar functionality but require verification of electrical specifications and pinout compatibility against the original design requirements.
