74AHCV05APWJ

Overview

The Nexperia 74AHCV05APWJ is a hex inverter featuring Schmitt trigger inputs and open-drain outputs, housed in a TSSOP14 (SOT402-1) package. It operates within a supply voltage range of 1.8 V to 5.5 V. The device supports mixed-mode voltage operation on all ports and includes IOFF circuitry for partial power-down applications. Typical propagation delay is 3.6 ns at 5 V, with low-level output voltage below 0.8 V at 3.3 V.

Feature Summary

• Schmitt trigger inputs transform slowly changing signals into sharply defined outputs
• Open-drain outputs enable active-LOW wired-OR or active-HIGH wired-AND functions
• IOFF circuitry prevents damaging backflow current during partial power-down

Applications

• Mixed voltage environments requiring signal translation
• Implementing wired-logic configurations via open-drain outputs
• Partial power-down system designs utilizing IOFF functionality

Procurement Notes

Verify the specific suffix 'J' against official Nexperia documentation to confirm tape-and-reel packaging details. Ensure the ordering code matches the required temperature range of -40 °C to +125 °C. Confirm RoHS compliance status directly from the manufacturer's latest product data sheet before finalizing procurement specifications.

Selection Notes

Select this component when hex inversion with hysteresis is required alongside open-drain output flexibility. The wide supply voltage range accommodates various logic families. Verify that the load capacitance requirements align with the specified dynamic characteristics for the target operating frequency and voltage conditions.

Part Context

This part belongs to the 74AHCV05A family of high-speed CMOS logic devices. It provides hex inverting functionality specifically designed for applications requiring robust noise immunity through Schmitt triggers. The open-drain configuration distinguishes it from standard push-pull inverters, allowing for direct interfacing with different voltage domains without additional level shifting components.

Replacement Considerations

Check for 74AHCV05APW as a potential equivalent if packaging variations are acceptable. Verify pinout compatibility and electrical parameters against the original datasheet before substitution.

FAQ

How does the IOFF circuitry function?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.

What logic functions can be implemented using the outputs?

The open-drain outputs can be connected together to implement active-LOW wired-OR or active-HIGH wired-AND functions.
