MAX3319ECAE+

Overview

The MAX3319ECAE+ is a single-channel, full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.25 V to 3.0 V and supports data rates up to 460 kbps. The device features AutoShutdown Plus technology, reducing supply current to 1 µA in shutdown mode. It includes an integrated dual charge pump requiring only four 0.1 µF capacitors. The component provides ±15 kV ESD protection on all pins and is housed in a 16-pin SSOP package.

Feature Summary

• AutoShutdown Plus feature for ultra-low power consumption
• Integrated dual charge pump with minimal external capacitance
• ±15 kV ESD protection on all RS-232 lines

Applications

• Portable battery-powered devices requiring low standby current
• Industrial control systems with serial communication interfaces
• Medical equipment with strict power management requirements

Procurement Notes

Verify the specific suffix 'CAE' against official datasheets to confirm temperature grade and packaging type. Ensure compatibility with 2.5 V logic levels. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when designing for 2.5 V systems requiring single-channel RS-232 connectivity. It is suitable for applications prioritizing low quiescent current over high-speed data transmission. Compare against MAX3316/MAX3317 if multiple channels or different voltage ranges are required.

Part Context

This part belongs to the MAX3316–MAX3319 family of low-voltage RS-232 transceivers. These devices utilize proprietary low-dropout transmitter output stages to achieve RS-232 performance from a single 2.5 V supply. The family is designed for portable electronics where power efficiency is critical.

Replacement Considerations

MAX3319EEAE+T: Same electrical specifications but in tape-and-reel packaging. MAX3319CAE: Non-RoHS compliant version of the same component.
