MAX3097ECEE

Overview

The MAX3097ECEE is a triple RS-485/RS-422 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 channel, identifying open-circuit, short-circuit, low differential voltage, and common-mode range violations. It includes a capacitor-programmable delayed fault output (ALARMD) to prevent erroneous alarms during slow edge rates. ESD protection is rated at ±15kV (Human Body Model) and ±15kV (IEC 1000-4-2 Air-Gap). The component is housed in a 16-pin QSOP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Triple high-speed receivers with dedicated fault-status outputs for A, B, and Z channels
• Capacitor-programmable delay on the ALARMD pin to ensure error-free operation at slow data rates
• Extended common-mode input range from -10V to +13.2V
• Robust electrostatic discharge protection meeting IEC 1000-4-2 Level 4 standards

Applications

• Motor-shaft encoder signal reception
• Telecommunications equipment
• Embedded systems requiring reliable differential signaling

Procurement Notes

Verify the specific ordering suffix 'CEE' to confirm the 16-pin QSOP package and commercial temperature range (0°C to +70°C). Ensure compatibility with existing board layouts designed for this form factor. Cross-reference the manufacturer's current production status as availability may vary. Confirm that the application environment does not exceed the absolute maximum ratings for supply voltage or input signals.

Selection Notes

Select the MAX3097ECEE when three independent receiver channels with fault detection are required in a compact surface-mount package. This part is suitable for designs needing extended common-mode tolerance and programmable fault blanking. Compare against the MAX3098E series if different fault threshold sensitivities are preferred. Ensure the system power supply remains within the specified 3V to 5.5V range for optimal performance.

Part Context

The MAX3097ECEE belongs to the MAX3097E/MAX3098E family of high-speed differential receivers. These devices are engineered for robust communication in noisy industrial environments. The MAX3097 variant provides three receivers with standard fault thresholds, while the MAX3098 offers adjustable sensitivity options. Both families share similar pinouts and functional blocks, facilitating design flexibility across different product lines.

Replacement Considerations

The MAX3097ECSE serves as a direct replacement offering the same electrical characteristics but utilizes a 16-pin SO package instead of QSOP. Designers must verify footprint compatibility when substituting packages. Other members of the MAX3097E family, such as the EESE or EEPE variants, provide extended temperature ranges (-40°C to +85°C) which may be necessary for harsher operating conditions.
