MAX3317EEUP

Overview

The MAX3317EEUP+ is a low-voltage RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.25 V to 3 V and supports data rates up to 460 kbps. The device features two drivers and two receivers in a full-duplex configuration, housed in a 20-TSSOP surface-mount package. It includes 300 mV receiver hysteresis for noise immunity and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports low-voltage operation down to 2.25 V for compatibility with modern logic families
• Provides full-duplex communication with integrated driver and receiver channels
• Includes 300 mV receiver hysteresis to enhance signal integrity in noisy environments

Applications

• Low-power serial communication interfaces
• Battery-operated mobile devices requiring minimal current consumption
• Industrial control systems utilizing RS-232 protocols

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical characteristics and packaging options. Confirm RoHS compliance status through authorized distributors or direct manufacturer channels before procurement. Ensure the component meets all environmental specifications required for the intended deployment environment.

Selection Notes

Select this component when designing systems that require RS-232 connectivity with strict low-voltage power constraints. It is suitable for applications where standard 5 V supplies are unavailable. Verify that the 460 kbps data rate meets system timing requirements and that the TSSOP-20 footprint aligns with PCB layout constraints.

Part Context

This part belongs to the MAX3316E-MAX3319E family of low-voltage RS-232 transceivers. These components are designed to replace traditional higher-voltage interface chips in portable electronics. The EEUP variant specifically denotes the extended industrial temperature range and tube packaging format.

Replacement Considerations

The MAX3317ECUP+ serves as a commercial grade alternative with a 0°C to 70°C operating range. Verify pinout compatibility and electrical parameter differences between the E and EC series variants before substitution.
