MAX3317EEAP+T

Overview

The MAX3317EEAP+T is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +2.25V to +3.0V supply and utilizes a proprietary low-dropout transmitter output stage with a dual charge pump. The device provides two drivers and two receivers, supporting data rates up to 460kbps. It features a 1µA shutdown mode accessible via the SHDN pin while keeping receivers active. The component is housed in a 20-pin SSOP package and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual charge-pump voltage converter generates internal ±4.4V and -4.3V supplies from a single low-voltage source
• AutoShutdown Plus feature enables ultra-low power consumption when idle or disconnected
• RS-232 compatible performance down to 2.25V supply voltage
• Guaranteed 460kbps data rate with worst-case loads

Applications

• Palmtop Computers
• Hand-Held Instruments
• GPS Systems
• Cellular Phones
• Pagers

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Cross-reference part numbers with authorized distributors to ensure authenticity and traceability before procurement.

Selection Notes

Select this component for applications requiring RS-232 communication in space-constrained, battery-powered devices. Ensure the system operates within the specified +2.25V to +3.0V supply range. Verify that the required data rate does not exceed 460kbps and that the 20-pin SSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to the MAX3316–MAX3319 family of 2.5V, 1µA, 460kbps RS-232-compatible transceivers. The MAX3317 specifically offers two drivers and two receivers with a manual shutdown control. It shares core architecture with the MAX3316, MAX3318, and MAX3319 but differs in shutdown functionality and available I/O configurations.

Replacement Considerations

Public confirmed substitute part numbers: MAX3316EAP+T, MAX3318EAP+T, MAX3319EAP+T.
