MAX6314US26D2+CD7

Supervisors Overview

The MAX6314US26D2+CD7 is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supplies in microprocessor and digital systems with a fixed reset threshold voltage of 2.63V. The device features a bidirectional RESET output compatible with processors like the 68HC11 and includes a debounced manual reset input. It operates within a supply voltage range up to 5.5V and an ambient temperature range of -40°C to +85°C, housed in a TO-253AA package.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional reset inputs
• Debounced manual reset input for user-initiated system resets
• Fixed preset threshold voltage eliminates need for external component adjustments

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems requiring compatibility with 68HC11 or similar bidirectional reset interfaces

Supervisors Procurement Notes

Verify the specific suffix CD7 against official Analog Devices documentation to confirm package type and compliance status. Ensure the bidirectional output requirement matches the target microprocessor interface. Confirm operating temperature and supply voltage ranges align with system specifications before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is required for bidirectional reset applications. It is suitable for designs needing manual reset capability without external debounce components. Consider the TO-253AA package constraints and the -40°C to +85°C operating range during thermal and mechanical design.

Supervisors Part Context

This part belongs to the MAX6314 family of low-power CMOS µP supervisory circuits. The family provides reliable reset generation for digital systems by eliminating external adjustments. Variants differ primarily in reset threshold voltages and package options while maintaining core bidirectional functionality.

Supervisors Replacement Considerations

Other MAX6314 variants with different threshold voltages (e.g., US33, US46) may serve as functional substitutes if the reset level is adjustable or acceptable. Verify pinout compatibility and bidirectional output support in any cross-reference.
