MAX3098EACSE+

Overview

The MAX3098EACSE+ is a triple RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3V to +5.5V supply and supports data rates up to 32Mbps. The device features fault-detection circuitry with independent alarm outputs for each receiver and a delayed general fault output. It provides ±15kV ESD protection via Human Body Model and IEC 1000-4-2 standards. The component is housed in a 16-pin SO package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Detects open-circuit, short-circuit, low differential voltage, and common-mode range violations
• Includes capacitor-programmable delay for the ALARMD output to prevent erroneous alarms at slow edge rates
• Offers extended common-mode input range from -10V to +13.2V

Applications

• Motor-shaft encoder receivers
• Telecommunications systems
• Embedded systems requiring high-speed signal reception

Procurement Notes

Verify the specific ordering suffix 'ACSE' against official documentation to confirm the 16-pin SO package and 0°C to +70°C temperature range. Ensure compatibility with system power supplies between 3V and 5.5V. Confirm that the required fault detection thresholds align with the MAX3098E specifications rather than the MAX3097E variants.

Selection Notes

Select this component when designing motor-control feedback systems or industrial applications requiring robust fault detection on RS-485/RS-422 lines. The MAX3098E variant specifically offers tighter differential fault thresholds compared to the MAX3097E. Consider the 16-pin QSOP alternative if board space constraints require a smaller footprint, as it is 40% smaller than standard industry solutions.

Part Context

This part belongs to the MAX3097E/MAX3098E family of high-speed receivers designed for motion control and industrial environments. The MAX3098E differs from the MAX3097E primarily in its fault-detection sensitivity thresholds. Both devices share identical pinouts and packaging options, facilitating direct interchangeability in designs where fault threshold adjustments are permissible.

Replacement Considerations

MAX3097EACSE+ shares the same package and temperature range but has different fault detection thresholds.
