MAX221EUE+T

Overview

The MAX221EUE+T is a single transmit/receive RS-232 transceiver powered by a +5V supply. It features an AutoShutdown function that reduces the supply current to 1µA when no valid signal is detected for 30µs. The device guarantees a data rate of 250kbps with worst-case loads of 3kΩ in parallel with 1000pF. It operates within a temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP package.

Feature Summary

AutoShutdown technology minimizes power consumption by disabling the charge pump and driver when idle, reducing supply current to 1µA without BIOS modifications.
Integrated dual charge pumps generate internal positive and negative voltages from a single +5V source using four external capacitors.
INVALID output pin indicates the presence of active RS-232 signals at the receiver input, enabling system-level power management.

Applications

Maintenance and diagnostic ports
Industrial systems
Telecommunications equipment
Set-top boxes

Procurement Notes

Verify the component matches the specific E-grade temperature rating (-40°C to +85°C) and the TSSOP-16 package configuration. Confirm the suffix +T indicates tape-and-reel packaging as per manufacturer specifications. Ensure compatibility with standard 0.1µF charge-pump capacitor requirements for proper voltage generation.

Selection Notes

Select this component for applications requiring low standby power in single-supply environments. It serves as a direct replacement for older MAX221 variants lacking enhanced ESD protection or extended temperature ranges. Consider the INVALID pin utility for host-based connection detection logic.

Part Context

This part belongs to the MAX220–MAX249 family of +5V-powered RS-232 drivers and receivers. The 'E' designation specifies the industrial temperature grade, while 'UE' denotes the 16-pin TSSOP package. The '+' suffix indicates lead-free compliance according to RoHS standards.

Replacement Considerations

The MAX221CUE+ offers identical functionality but is rated for commercial temperatures (0°C to +70°C). The MAX221EEUE+ provides enhanced ±15kV ESD protection compared to the standard MAX221E series.
