74AC14PC

Overview

The onsemi 74AC14PC is a hex inverter utilizing AC logic series technology. It features six Schmitt trigger inputs for noise immunity and operates within a supply voltage range of 2V to 6V. The device provides maximum output currents of 24mA (low) and -24mA (high). It exhibits a maximum propagation delay of 15ns at specified load conditions. Operating temperatures span from -40°C to +85°C. The component is housed in a 14-pin PDIP W package with dimensions of 19.3mm length, 7.62mm width, and 4.57mm height.

Feature Summary

• Integrates six independent inverters with Schmitt trigger input thresholds to enhance signal integrity and noise rejection.
• Constructed using high-speed CMOS technology compatible with standard CMOS outputs while offering improved switching characteristics.
• Designed for surface-mount or through-hole integration via the 14-pin dual in-line package format.

Applications

• Waveform shaping and conversion of slow-rise signals into clean digital pulses
• Oscillator circuit implementations requiring stable threshold triggering
• Clock signal conditioning and buffering in digital systems

Procurement Notes

Verify the specific suffix 'PC' corresponds to the 14-pin PDIP W package configuration rather than SOIC or TSSOP variants. Confirm RoHS compliance status as indicated in official datasheets. Ensure ordering quantities align with manufacturer minimums if applicable. Cross-reference pinout diagrams to prevent orientation errors during assembly. Validate temperature ratings against environmental operating requirements.

Selection Notes

Select this component when six isolated inverting channels with hysteresis are required. The AC logic family offers faster switching speeds compared to standard HC series devices. Consider the PDIP package for prototyping or applications where through-hole mounting is preferred over surface mount alternatives. Verify voltage compatibility with the 2V to 6V operational range before integration.

Part Context

This part belongs to the 74AC14 logical inverter family produced by onsemi. It serves as a fundamental building block for digital logic circuits requiring inversion and noise filtering. The AC series represents an evolution in CMOS performance, balancing speed and power consumption. Related variants include SOIC and TSSOP packages such as 74AC14SCX and 74AC14MTCX.

Replacement Considerations

Compatible substitutes include MC74AC14DR2G and 74AC14SCX. These alternatives maintain identical logical functions but differ in packaging styles such as SOIC or TSSOP. Verify pin compatibility and electrical specifications before substitution to ensure seamless integration without redesigning the footprint.

FAQ

What is the function of the Schmitt trigger inputs?

The Schmitt trigger inputs provide hysteresis, which prevents output oscillation caused by noisy or slowly changing input signals by defining distinct high-to-low and low-to-high transition thresholds.

What is the maximum propagation delay for this device?

The maximum propagation delay is 15ns under specified load conditions, ensuring fast switching performance suitable for high-speed digital applications.
