MAX3316EAE

Overview

The MAX3316EAE is a low-power, RS-232-compatible transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single +2.25V to +3.0V supply and features two drivers and two receivers for full-duplex communication. The device supports data rates up to 460kbps with a propagation delay of 0.175µs. It requires only four 0.1µF capacitors for external charge pump operation. The typical operating supply current is 1mA. It is housed in an SSOP-16 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Proprietary low-dropout transmitter output stage enables RS-232 performance at low voltages
• Minimal external component requirement using only four 0.1µF capacitors
• Guaranteed operation at data rates up to 460kbps

Applications

• Portable battery-powered equipment requiring RS-232 connectivity
• Industrial control systems with limited power budgets
• Communication modules in space-constrained designs

Procurement Notes

Verify the specific suffix 'EAE' against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the SSOP-16 configuration. Confirm that the required voltage range aligns with the system's power supply architecture before procurement.

Selection Notes

Select this component when a dual-driver, dual-receiver RS-232 interface is needed with minimal external capacitance. It is suitable for applications powered by a single low-voltage source between 2.25V and 3.0V. Consider the 460kbps speed limit and SSOP-16 package constraints during design integration.

Part Context

This part belongs to the MAX3316–MAX3319 series of low-power RS-232 transceivers. These devices share a common architecture utilizing a dual-charge pump to generate necessary voltage levels from a single low-voltage supply. The series is designed for portable applications where power consumption and board space are critical factors.

Replacement Considerations

Direct substitutes include other parts from the MAX3316–MAX3319 family, such as the MAX3317EAE or MAX3318EAE, provided pinouts and functional differences like shutdown modes are accounted for. Verify electrical specifications match the original design requirements.
