MAX3232IPWRE4

Overview

The MAX3232IPWRE4 is a dual RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex communication. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device integrates two drivers and two receivers in a single package. It features low supply current consumption of approximately 1 mA and includes ESD protection rated at 15 kV. The component functions reliably across an extended temperature range from -40°C to +85°C. It is housed in a 16-TSSOP surface-mount package with a width of 4.40 mm.

Feature Summary

• Integrates dual drivers and receivers for full-duplex RS-232 communication
• Operates on a single 3 V to 5.5 V power supply
• Provides 15 kV electrostatic discharge (ESD) protection on all lines
• Features low power consumption suitable for battery-powered applications

Applications

• Portable equipment requiring serial communication interfaces
• Industrial control systems operating in harsh environments
• Modems and portable instruments with RS-232 connectivity needs

Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's official documentation to confirm compliance details and material composition. Ensure the ordering information matches the exact package type and temperature grade required for the design. Cross-reference the datasheet revision history to validate current manufacturing status and any potential changes in pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with low power constraints. The 16-TSSOP package is suitable for space-constrained printed circuit board layouts. Verify that the system voltage falls within the 3 V to 5.5 V operational range. Consider the 250 kb/s data rate limit for high-speed application compatibility. Ensure thermal management meets the -40°C to +85°C operating requirements.

Part Context

This part belongs to the MAX3232 family of RS-232 transceivers from Texas Instruments. It shares core functionality with variants like the MAX3232IPWR but may differ in packaging or environmental specifications due to the 'E4' suffix. The family is widely used for converting TTL/CMOS levels to RS-232 standards. It serves as a direct replacement for older MAX232-based designs with improved performance and lower power consumption.

Replacement Considerations

The MAX3232IPWR is a compatible alternative within the same series. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Check for any differences in package dimensions or thermal performance between the 'E4' variant and standard versions.
