CD74AC14M

Inverter Gates Overview

The CD74AC14M is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It belongs to the AC logic family and features six independent inverters within a single package. The device operates with a supply voltage range of 1.5 V to 5.5 V and supports an operating temperature range from -55 °C to +125 °C. It utilizes a 14-pin SOIC surface-mount package. Key electrical characteristics include a maximum propagation delay of 10.2 ns at 3.3 V and 7.3 ns at 5 V under a 50 pF load. Output drive capabilities are specified at ±24 mA for both high and low states.

Inverter Gates Feature Summary

• Integrates six independent Schmitt-trigger inverters for signal conditioning
• Provides robust noise immunity through defined input hysteresis thresholds
• Supports wide supply voltage operation from 1.5 V to 5.5 V
• Features high-current push-pull outputs capable of driving standard CMOS loads

Inverter Gates Applications

• Waveform shaping of slow-rise or slow-fall digital signals
• Noise filtering in noisy industrial environments
• Pulse generation circuits requiring precise timing edges
• Oscillator circuits utilizing RC feedback networks

Inverter Gates Procurement Notes

Verify the specific suffix designation against current manufacturer documentation, as packaging and lead frame materials may vary. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for active production status or obsolescence notices, as legacy logic families may have limited availability or replacement part numbers available from authorized distributors.

Inverter Gates Selection Notes

Select this component when application requirements demand Schmitt-trigger action to eliminate signal chatter on noisy lines. The AC series offers a balance between speed and power consumption suitable for general-purpose digital systems. Ensure the chosen package variant matches the PCB footprint and thermal management requirements of the design.

Inverter Gates Part Context

This component is part of the Texas Instruments CD74ACxx logic family, designed for high-speed CMOS applications. It serves as a functional equivalent to industry-standard 74AC14 devices. The device is commonly used in conjunction with other AC series logic gates to build complex digital control systems requiring reliable signal inversion and noise rejection.

Inverter Gates Replacement Considerations

Direct pin-compatible alternatives include the CD74ACT14M for 5 V-only applications. Cross-manufacturer equivalents such as MC74AC14 or HD74AC14 may be considered if electrical specifications align with system requirements.
