MAX3316EUP

Overview

The MAX3316EUP is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for low-power serial communication applications. 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, providing full-duplex communication capabilities. Key electrical specifications include a typical propagation delay of 0.175 µs and an operating supply current of 1 mA. It is housed in a TSSOP-16 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Dual driver and receiver configuration for full-duplex RS-232 communication
• Low power consumption with 1 mA operating supply current
• Supports high-speed data transmission up to 460 kbps
• Operates on a single 2.25 V to 3 V power supply

Applications

• Portable battery-powered devices requiring RS-232 connectivity
• Industrial control systems with low-voltage logic interfaces
• Embedded systems needing compact serial communication solutions

Procurement Notes

Verify the specific suffix 'EUP' against official datasheets to confirm the TSSOP-16 package type and commercial/industrial temperature rating. Ensure compatibility with 2.25 V to 3 V supply rails before procurement. Cross-reference manufacturer part numbers to avoid confusion with similar series variants that may differ in pinout or performance characteristics.

Selection Notes

Select this component when designing circuits that require dual RS-232 channels with minimal power draw. It is suitable for systems powered by single-cell lithium batteries or regulated 3 V supplies. Consider the TSSOP-16 footprint for PCB layout constraints. Verify that the required data rate does not exceed 460 kbps and that the operating environment stays within the specified temperature limits.

Part Context

This part belongs to the MAX3316E series of RS-232 transceivers. It is distinct from higher-voltage variants like the MAX3232, which operate at 3 V to 5.5 V. The MAX3316EUP is optimized for low-voltage applications, offering a balance between performance and power efficiency compared to standard RS-232 drivers.

Replacement Considerations

Direct substitutes may include other Maxim Integrated low-voltage RS-232 transceivers such as the MAX3232EUP if voltage levels can be adapted. Verify pin-to-pin compatibility and ensure the replacement supports the same data rate and package dimensions.
