CD74HC123MG4

Multivibrators Overview

The CD74HC123MG4 is a dual retriggerable monostable multivibrator manufactured by Texas Instruments. It belongs to the 74HC series of high-speed CMOS logic devices and features two independent circuits within a single package. The component operates on a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 10-VSSOP package. It provides balanced push-pull outputs with a maximum output current of 5.2 mA for both high and low states. The device is designed for applications requiring precise pulse timing and signal conditioning.

Multivibrators Feature Summary

• Dual-channel architecture providing two independent retriggerable monostable multivibrators
• High-speed CMOS technology enabling fast propagation delays suitable for digital timing applications
• Retriggerable functionality allowing pulse width extension upon receiving new trigger signals
• Wide operating temperature range supporting industrial and commercial environments

Multivibrators Applications

• Pulse generation and timing control circuits
• Frequency division and counting systems
• Waveform shaping and signal conditioning
• Delay line implementations in digital logic designs

Multivibrators Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm RoHS compliance status and lead times, as this indicates environmental specifications. Confirm the package type matches the design requirements, as variations exist between SOIC and VSSOP formats for similar part numbers. Ensure the source document explicitly lists the CD74HC123MG4 to avoid confusion with standard or non-green variants.

Multivibrators Selection Notes

Select this component when a dual-channel solution is required for monostable operations within a compact surface-mount footprint. Compare the 10-VSSOP package dimensions against available board space constraints relative to the 16-SOIC alternatives. Evaluate the 2 V to 6 V supply range compatibility with the target system voltage levels. Consider the 5.2 mA drive strength sufficient for the intended load capacitance and fan-out requirements.

Multivibrators Part Context

This part is a member of the Texas Instruments 74HC family, which offers high-speed operation comparable to LS logic but with lower power consumption. The CD74HC123 variant specifically focuses on monostable multivibrator functions. The 'G4' suffix typically denotes Green/RoHS-compliant manufacturing processes. It serves as a functional alternative to other 74HC123 derivatives differing primarily in packaging or environmental certifications.

Multivibrators Replacement Considerations

Direct substitutes include the CD74HC123MT and CD74HC123M96 from Texas Instruments, which share identical logical functions. Verify pinout compatibility if replacing with packages such as SOIC or TSSOP. Cross-reference with Nexperia 74HC123D equivalents for potential sourcing options while ensuring electrical parameter alignment.
