74AHCT07APWJ

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT07APWJ is a hex buffer with open-drain outputs designed for operation within a supply voltage range of 4.5 V to 5.5 V. It features TTL-compatible inputs and Schmitt-trigger action for noise immunity. The device supports mixed-mode voltage operation, allowing translation from 3.3 V to 5 V. Key electrical parameters include a typical propagation delay (tPZL) of 3.4 ns at 5 V, a low-level output voltage (VOL(p)) below 0.8 V at VCC = 5 V, and an operating temperature range from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Hex buffer configuration with open-drain outputs enabling active-LOW wired-OR or active-HIGH wired-AND functions.
• TTL-compatible inputs with Schmitt-trigger action to tolerate slower input rise and fall times.
• IOFF circuitry provides partial power-down mode operation by disabling outputs to prevent backflow current.

Buffers, Drivers, Receivers, Transceivers Applications

• Translating signals from 3.3 V logic levels to 5 V systems.
• Implementing wired-OR or wired-AND logic configurations in digital circuits.
• Mixed-mode voltage operation environments requiring level shifting.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure the procurement channel sources genuine Nexperia components to guarantee compliance with the specified electrical characteristics and reliability standards outlined in the product data sheet.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a hex buffer with open-drain outputs is required for 5 V logic applications. It is suitable for designs needing TTL compatibility and Schmitt-trigger inputs to handle noisy signals. Consider the TSSOP14 package constraints and the need for external pull-up resistors due to the open-drain output structure.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74AHCT07A belongs to the AHCT logic family, which combines high-speed CMOS performance with TTL-compatible inputs. This series is designed for 5 V applications where direct interfacing with TTL devices is necessary. The APWJ variant specifically denotes the TSSOP14 plastic thin shrink small outline package version.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements must match the hex buffer open-drain specification and AHCT logic family. Verify pinout compatibility and ensure the substitute part supports the 4.5 V to 5.5 V supply range and -40 °C to +125 °C temperature specifications.

Buffers, Drivers, Receivers, Transceivers FAQ

Can the 74AHCT07APWJ be used to translate between 3.3 V and 5 V logic levels?

Yes, the device is designed to operate over a VCC range from 4.5 V to 5.5 V, and its TTL-compatible inputs allow it to be used to translate from 3.3 V to 5 V.

What is the function of the IOFF circuitry in this device?

The IOFF circuitry provides partial power-down mode operation by disabling the output, which prevents damaging backflow current through the device when it is powered down.
