74AC14SJX

Overview

The onsemi 74AC14SJX is a hex inverter integrated circuit featuring Schmitt trigger inputs, housed in a 14-pin SOP surface-mount package. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range of -40°C to +85°C. The device provides a maximum propagation delay of 10ns at 5V with 50pF load, ensuring fast switching performance. Output drive capabilities include a maximum high-level output current of -24mA and a low-level output current of 24mA. Quiescent current is limited to a maximum of 2µA.

Feature Summary

• Hex inverter configuration with six independent Schmitt trigger channels for noise immunity
• High-speed logic operation with low propagation delay characteristics
• Robust output drive capability supporting standard CMOS loads
• Wide operating voltage range compatible with various digital systems

Applications

• Signal conditioning and waveform shaping in digital circuits
• Clock signal generation and timing applications
• Oscillator circuits requiring hysteresis for stability
• Pulse width modulation (PWM) signal processing

Procurement Notes

Verify the specific suffix SJX corresponds to the 14-SOP package and tape-and-reel packaging format. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to integration. Ensure design compatibility with the specified voltage and temperature ranges for reliable operation.

Selection Notes

Select this component when hex Schmitt trigger inverters are required in a compact surface-mount form factor. The AC series offers faster switching speeds compared to standard HC variants. Verify that the 14-SOP footprint matches the PCB layout requirements and that the output current specifications meet the load demands of the connected circuitry.

Part Context

This part belongs to the 74AC logic family, known for high-speed CMOS technology. It serves as a functional equivalent to other hex Schmitt trigger inverters but is distinguished by its specific package type and electrical characteristics. The 74AC14 series is widely used in general-purpose digital logic applications requiring noise rejection and clean signal transitions.

Replacement Considerations

Check for direct pin-compatible alternatives such as the 74AC14SCX or 74AC14MTCX from onsemi, noting differences in package style (SOIC vs TSSOP). Other manufacturers may offer similar hex Schmitt trigger inverters; verify electrical parameters including propagation delay and output current before substitution.
