Overview
The MAX221ECAE+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. The device provides ±15kV ESD protection on I/O pins and guarantees data rates up to 250kbps. It operates within a temperature range of 0°C to +70°C and is housed in a 16-pin SSOP package.
Feature Summary
- AutoShutdown functionality for ultra-low power consumption
- Enhanced electrostatic discharge protection on RS-232 I/O pins
- Integrated dual charge-pump voltage converter
Applications
- Maintenance and diagnostic ports
- Industrial systems
- Telecommunications equipment
- Set-top boxes
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status through the manufacturer's latest release notes or component marking details before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring low standby power without BIOS modifications. Ensure the design accommodates the required external capacitors for the internal charge pumps. Verify that the operating environment remains within the specified commercial temperature limits.
Part Context
This part belongs to the MAX221 family of single RS-232 transceivers. The 'E' suffix indicates an extended temperature grade, while 'CAE' specifies the commercial variant with a 16-pin SSOP package. It serves as a direct interface between TTL/CMOS logic and RS-232 serial communication lines.
Replacement Considerations
Cross-reference with other MAX221 variants such as MAX221EEAE+T for extended temperature requirements. Verify pin compatibility and electrical characteristics against alternative single-channel RS-232 transceivers from different manufacturers if sourcing constraints exist.
FAQ
How does the AutoShutdown feature reduce power consumption?
It detects invalid signal levels on the receiver input for 30µs and shuts off the charge pump and driver, reducing supply current to 1µA.
What is the maximum guaranteed data rate?
The device guarantees a data rate of 250kbps under worst-case load conditions.
Can polarized capacitors be used for the charge pump?
Yes, either polarized or nonpolarized capacitors are acceptable, provided polarity is observed if polarized types are selected.
