CD74HC123PWRG4

Multivibrators Overview

The CD74HC123PWRG4 is a dual monostable multivibrator from the Texas Instruments HC logic family, housed in a TSSOP-16 surface-mount package. It operates within a supply voltage range of 2 V to 6 V, with typical operating voltages at 2.5 V, 3.3 V, and 5 V. The device features a maximum supply current of 8 uA and output currents of ±5.2 mA. Propagation delays are specified at 250 ns, 50 ns, and 43 ns. It functions across an extended temperature range from -55°C to +125°C.

Multivibrators Feature Summary

• Dual independent monostable multivibrator circuits integrated into a single high-speed CMOS package
• Retriggerable functionality allowing pulse width extension upon additional trigger events
• Compatible with standard 2 V to 6 V CMOS logic power supplies

Multivibrators Applications

• Timing delay generation for digital signal processing
• Pulse width modulation circuit implementation
• Frequency division in clock management systems

Multivibrators Procurement Notes

Verify the G4 suffix indicates RoHS compliance and green manufacturing options as per Texas Instruments standards. Confirm the PWR designation corresponds to the TSSOP-16 package variant. Ensure the component matches the specific propagation delay requirements for your application timing constraints before finalizing procurement.

Multivibrators Selection Notes

Select this component when dual retriggerable monostable circuits are required in a compact surface-mount form factor. The HC series offers high-speed operation suitable for general-purpose digital applications. Consider the extended temperature range if the environment exceeds standard commercial limits. Verify pin compatibility with existing PCB footprints designed for the TSSOP-16 package.

Multivibrators Part Context

This part belongs to the CD74HC4538/CD74HC123 family of monostable multivibrators manufactured by Texas Instruments. It shares the HC logic series characteristics, providing high noise immunity and low power consumption. The device is part of a broader portfolio of timing and logic ICs designed for industrial and consumer electronics applications requiring precise pulse generation.

Multivibrators Replacement Considerations

The CD74HC123PWR is a direct functional equivalent without the G4 suffix. Other variants include CD74HC123MT in SOIC packaging. Cross-reference datasheets to ensure identical pinouts and electrical specifications before substitution.
