MAX3316ECUP-T

Overview

The MAX3316ECUP-T is a dual transmitter and dual receiver RS-232 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.25 V to 3 V, with a typical operating voltage of 2.5 V. The device supports data rates up to 460 kbps and features full-duplex communication capability. It is housed in a 16-pin SSOP package and includes two drivers and two receivers. The component lacks an integrated shutdown mode and does not provide electrostatic discharge (ESD) protection on its I/O pins.

Feature Summary

• Provides full-duplex RS-232 signal conversion for serial communication interfaces.
• Operates at low supply voltages suitable for portable and battery-powered applications.
• Integrates charge pump circuitry to generate required RS-232 voltage levels from a single low-voltage supply.

Applications

• Portable computing devices requiring serial connectivity.
• Battery-operated instrumentation systems.
• Industrial control panels utilizing RS-232 protocols.

Procurement Notes

Verify the specific suffix configuration when sourcing, as the absence of ESD protection distinguishes this variant from other models in the series. Confirm package integrity upon receipt, as the SSOP form factor requires careful handling during surface-mount assembly processes to ensure reliable electrical connections.

Selection Notes

Select this component only if ESD protection is unnecessary or handled externally, as it lacks built-in protection mechanisms. Ensure the design environment strictly adheres to the 2.25 V to 3 V supply voltage limits. Verify that the 460 kbps data rate meets system requirements, noting that higher-speed alternatives exist within the manufacturer's portfolio.

Part Context

This part belongs to the MAX3316E family of low-voltage RS-232 transceivers designed for power-sensitive applications. Unlike many contemporaries, this specific model omits ESD protection and shutdown features to optimize performance within its defined operational constraints. It serves as a specialized interface solution for systems where external protection is already implemented.

Replacement Considerations

The MAX3318EEUP+ offers similar functionality but includes 15 kV ESD protection and a shutdown pin. The MAX3317EEUP+T provides comparable performance with integrated ESD protection. Verify pin compatibility and functional differences before substituting these alternatives.
