74LV07ATPWJ

Overview

The Nexperia 74LV07ATPWJ 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, enabling translation from 3.3 V logic levels. The device incorporates Schmitt-trigger action at all inputs to tolerate slower rise and fall times. It includes IOFF circuitry for partial power-down applications, preventing damaging backflow current when powered down. The component is specified for ambient temperatures ranging from -40 °C to +125 °C.

Feature Summary

• Hex buffer configuration with open-drain outputs supporting active-LOW wired-OR or active-HIGH wired-AND functions.
• TTL-compatible inputs allow direct interfacing with 3.3 V devices in mixed-mode voltage environments.
• Schmitt-trigger action provides tolerance for slower input signal transitions.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.

Applications

• Translation between 3.3 V and 5 V logic levels
• Implementation of active-LOW wired-OR functions
• Implementation of active-HIGH wired-AND functions

Procurement Notes

Verify the specific ordering suffix 'PWJ' against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required temperature range and ESD protection levels defined in the product data sheet before finalizing procurement.

Selection Notes

Select this component for designs requiring hex buffering with open-drain outputs in 5 V systems. It is suitable for translating signals from 3.3 V sources due to TTL-compatible inputs. Consider the TSSOP14 package dimensions and thermal derating characteristics if operating near the upper temperature limits.

Part Context

The 74LV07AT belongs to the LV (Low-Voltage) logic family from Nexperia, optimized for 5 V operation. Unlike LVC variants that support wider voltage ranges, this series focuses on high-speed performance and robustness in standard 5 V digital circuits. It serves as a fundamental building block for signal conditioning and level shifting in mixed-voltage digital systems.

Replacement Considerations

Check for compatible hex buffers with open-drain outputs in the same logic family. Verify pin compatibility and electrical characteristics such as propagation delay and output drive capability before substituting.
