CD54HCT4538F3A

Multivibrators Overview

The CD54HCT4538F3A is a dual retriggerable precision monostable multivibrator manufactured by Harris Corporation. It belongs to the HC/UH series and utilizes CMOS technology housed in a 16-pin ceramic DIP package (CDIP16). The device operates within a temperature range of -55°C to 125°C and supports standard HCT logic levels.

Multivibrators Feature Summary

• Dual independent monostable multivibrator circuits
• Retriggerable operation for pulse width adjustment
• Precision timing characteristics
• High-speed CMOS construction

Multivibrators Applications

• Pulse generation
• Timing delays
• Waveform shaping

Multivibrators Procurement Notes

Verify manufacturer origin as Harris Corporation or authorized successor entities like Renesas. Confirm package type is CDIP16 ceramic. Check RoHS compliance status, which may be non-compliant for older Harris batches. Ensure pinout compatibility with target PCB footprint.

Multivibrators Selection Notes

Select this component when dual precision monostable functionality is required in harsh environments. The HCT series ensures TTL compatibility while maintaining CMOS low power consumption. Verify supply voltage requirements match system design constraints before integration.

Multivibrators Part Context

This part is part of the broader CD54HC/CD54HCT family of high-speed CMOS logic devices. It shares packaging and thermal specifications with other Harris military-grade components. The F3A suffix typically denotes specific tape-and-reel or bulk packaging variations within the ceramic DIP format.

Multivibrators Replacement Considerations

Compatible substitutes include CD54HC4538F from Texas Instruments and Intersil. Verify functional equivalence regarding retriggerability and output polarity. Cross-reference pinouts to ensure direct replacement without circuit modification.
