CD74HCT221M96

Multivibrators Overview

The CD74HCT221M96 is a dual monostable multivibrator manufactured by Texas Instruments, belonging to the 74HCT logic series. It features two independent circuits housed in a 16-SOIC surface-mount package with an exposed pad (M96 suffix). The device operates on a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 18 ns. It provides output currents of 4 mA for both high and low states. The component includes Schmitt trigger inputs and functions within a temperature range of -55°C to 125°C.

Multivibrators Feature Summary

• Dual monostable multivibrator configuration with two independent circuits per package
• Schmitt trigger inputs provide noise immunity and clean signal transitions
• Silicon-gate CMOS technology ensures compatibility with LSTTL logic levels while maintaining low power consumption

Multivibrators Applications

• Timing delays and pulse generation in digital systems
• Debouncing switches or contacts
• Pulse width modulation circuits

Multivibrators Procurement Notes

Verify the specific ordering suffix M96 to confirm the 16-SOIC package type and tape-and-reel packaging format. Confirm RoHS3 compliance status as indicated in official documentation. Ensure the design accommodates the specified operating temperature range of -55°C to 125°C. Cross-reference the manufacturer part number against current datasheets to validate any recent product change notices or end-of-life statuses.

Multivibrators Selection Notes

Select this component when TTL-compatible speed is required alongside CMOS power efficiency. The 18 ns propagation delay suits applications needing faster response than standard HC series devices. Verify that the 4 mA output drive capability meets load requirements. Consider the 16-SOIC footprint constraints during PCB layout. Ensure input voltages remain within the 4.5 V to 5.5 V supply limits to maintain logical integrity.

Multivibrators Part Context

This device is part of the broader 74HCT family, designed to bridge the performance gap between standard CMOS and Low-power Schottky TTL logic. The 'CD' prefix typically denotes commercial grade temperature ranges in Texas Instruments nomenclature, although this specific part extends to industrial extremes. It serves as a direct functional replacement for other dual monostable multivibrators in legacy designs requiring HCT-level interfacing.

Multivibrators Replacement Considerations

Direct substitutes include other 74HCT221 variants from Texas Instruments such as the CD74HCT221M or CD74HCT221E, provided pinouts and electrical characteristics match. Verify package compatibility if transitioning from DIP to SOIC formats.
