MAX3227IDBR

Overview

The MAX3227IDBR is a single-channel RS-232 transceiver manufactured by Texas Instruments, operating within a 3.0V to 5.5V supply voltage range. It supports data rates up to 1Mbps and features full-duplex communication with one driver and one receiver. The device incorporates AutoShutdown Plus technology for power management and provides ±15kV ESD protection on all pins. It is housed in a 16-pin SSOP package and operates over an industrial temperature range of -40°C to +85°C.

Feature Summary

AutoShutdown Plus functionality automatically reduces supply current during idle periods or when the transmitter is inactive.
Integrated charge pump generates required RS-232 voltage levels from a single low-voltage supply.
Robust electrostatic discharge protection ensures reliability in harsh environments.

Applications

Portable battery-powered equipment requiring low standby current
Industrial control systems with serial communication interfaces
Modems and portable instruments

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Confirm that the specific suffix IDBR corresponds to the tape-and-reel packaging format intended for automated assembly processes. Ensure compatibility with the target system's voltage levels and signal integrity requirements before finalizing procurement.

Selection Notes

Select this component for applications demanding minimal quiescent current and high noise immunity. Compare against the TRS3227EIDBR for potential pin-compatible alternatives from Texas Instruments. Evaluate the trade-off between the 1Mbps speed limit and the ultra-low power consumption benefits offered by the AutoShutdown feature.

Part Context

This part belongs to the MAX3227 family of single-channel RS-232 transceivers. It shares architectural similarities with the MAX3221 but offers higher data rate capabilities. The device is designed to replace older multi-supply RS-232 solutions by integrating necessary voltage generation internally.
