SA14584BDR2

Overview

The SA14584BDR2 is a hex Schmitt trigger inverter manufactured by onsemi, belonging to the MC14584B series. It utilizes CMOS technology with P-channel and N-channel enhancement mode devices in a monolithic structure. The component operates within a supply voltage range of 3 V to 18 V. It features six independent circuits in a 14-pin SOIC package. Key electrical parameters include a maximum propagation delay of 250 ns at lower voltages, reducing to 80 ns at higher voltages. Output currents are specified at 4.2 mA for both high and low states. The device supports surface mount installation and functions across an operating temperature range from -55°C to +125°C.

Feature Summary

• Hex Schmitt trigger configuration providing noise immunity through hysteresis
• CMOS construction ensuring low power consumption and high noise margins
• Wide supply voltage operation capability from 3 V to 18 V
• Industrial temperature range support for harsh environment reliability

Applications

• Signal conditioning and waveform shaping
• Debouncing mechanical switches
• Pulse generation circuits
• Oscillator applications requiring stable switching thresholds

Procurement Notes

Verify the exact part number suffix against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 14-pin SOIC-N variant. Cross-reference moisture sensitivity levels and handling requirements prior to assembly. Confirm that the specific revision matches design input requirements for propagation delay and output drive characteristics.

Selection Notes

Select this component when hex Schmitt trigger functionality is required in a compact surface-mount format. The wide voltage range allows flexibility in system power design. Consider the propagation delay specifications relative to signal frequency requirements. Verify thermal performance within the -55°C to +125°C range for the intended application environment. Compare against standard logic families if higher speed or different packaging is needed.

Part Context

This device is part of the MC14584B family of hex Schmitt triggers. It shares functional similarities with other CMOS inverters but distinguishes itself through built-in hysteresis for improved noise tolerance. The series is designed for general-purpose digital logic applications where clean signal transitions are critical despite noisy input conditions.

Replacement Considerations

Direct substitutes may include MC14584BDTR2G or MC14584BDR2G from onsemi, which share identical logical functions and pinouts. Verify package dimensions and electrical parameters match before substitution.
