CD74HC221PWR

Multivibrators Overview

The CD74HC221PWR is a dual monostable multivibrator from the Texas Instruments HC logic family, housed in a 16-pin TSSOP surface-mount package. It operates on a supply voltage range of 2 V to 6 V and supports an operating temperature range of -55 °C to +125 °C. The device features Schmitt-trigger inputs for noise immunity and provides complementary outputs. Key electrical parameters include a maximum propagation delay of 210 ns at 2 V and output currents of ±5.2 mA.

Multivibrators Feature Summary

• Dual independent monostable multivibrator circuits
• Schmitt-trigger inputs for improved noise rejection
• Complementary output configurations
• Wide operating voltage and temperature ranges

Multivibrators Applications

• Timing pulse generation
• Frequency division
• Waveform shaping

Multivibrators Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings against current manufacturer documentation prior to procurement. Ensure compatibility with standard surface-mount assembly processes.

Multivibrators Selection Notes

Select this component for designs requiring dual monostable functions within space-constrained PCB layouts. The TSSOP package offers a compact footprint suitable for high-density assemblies. Verify that the required propagation delay and output drive capabilities align with the system's timing constraints and load requirements.

Multivibrators Part Context

This part belongs to the CD74HC221 series of dual monostable multivibrators. It is functionally compatible with other industry-standard monostable devices but utilizes Texas Instruments' HC CMOS technology. The PWR suffix specifically denotes the plastic small-outline package type used in modern surface-mount electronics manufacturing.

Multivibrators Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74HC221 series if different packaging or performance characteristics are needed. Verify functional equivalence regarding propagation delays and supply voltage ranges before substituting.
