CD74HC423MT

Multivibrators Overview

The CD74HC423MT is a dual monostable multivibrator from the Texas Instruments 74HC series, housed in a 16-SOIC surface-mount package. It operates on a supply voltage range of 2 V to 6 V with a propagation delay of 25 ns. The device provides high and low output currents of 5.2 mA each and functions within an operating temperature range of -55°C to 125°C. It contains two independent circuits without Schmitt trigger inputs.

Multivibrators Feature Summary

• Dual monostable multivibrator configuration for timing applications
• High-speed CMOS logic technology for efficient operation
• Wide operating voltage range supporting various digital systems
• Extended industrial temperature rating for harsh environments

Multivibrators Applications

• Pulse generation and shaping circuits
• Timing delay elements in digital logic systems
• Debouncing switches or contacts
• Frequency division and pulse width modulation

Multivibrators Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm package integrity upon receipt as the part is sensitive to moisture despite MSL Level 1 classification. Check for RoHS3 compliance markers on packaging. Validate lot codes against manufacturer records to ensure consistency with design specifications.

Multivibrators Selection Notes

Select this component when dual independent monostable functionality is required in a compact SOIC footprint. Consider the 2V to 6V supply range compatibility with existing system rails. Evaluate the 25 ns propagation delay against circuit speed requirements. Ensure thermal management supports the -55°C to 125°C operational range if deployed in extreme conditions.

Multivibrators Part Context

This device belongs to the CD74HC(T)423 family of high-speed CMOS logic devices. It shares functional similarities with other monostable multivibrators but offers specific HC-series performance characteristics. The MT suffix indicates the 16-SOIC package variant designed for surface-mount assembly processes.

Multivibrators Replacement Considerations

CD74HC423M96 is a direct substitute offering identical functionality in the same package type.
