SN74ACT04NSR

Overview

The SN74ACT04NSR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74ACT logic series. It features six independent inverters housed in a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum low-level output current of 24 mA and a high-level output current of -24 mA. Propagation delay is specified at 8.5 ns under standard test conditions of 50 pF load capacitance at 5 V. The component functions across an extended industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Contains six independent inverting gates for signal inversion applications
• Provides high drive capability with 24 mA output current sourcing and sinking
• Operates on a single 5 V power supply compatible with TTL input levels

Applications

• Signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Waveform shaping and pulse modification

Procurement Notes

Verify the specific suffix 'NSR' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and pinout compatibility. Ensure that the operating environment remains within the specified -40 °C to +85 °C temperature range to maintain performance specifications. Confirm RoHS compliance status through the manufacturer's latest product data sheet before finalizing procurement.

Selection Notes

Select this component when a hex inverter function is required with CMOS-compatible inputs and TTL-compatible outputs. The 74ACT series offers faster switching speeds compared to standard 74LS devices while maintaining similar pinouts. Consider the SOIC-14 package dimensions for PCB layout constraints and verify that the 5 V supply voltage aligns with the system design requirements.

Part Context

This part belongs to the Texas Instruments 74ACT family of advanced CMOS logic devices. The 74ACT series bridges the performance gap between older TTL technologies and modern CMOS solutions, providing high-speed operation with robust noise immunity. The SN74ACT04 specifically implements the standard hex inverter logic function commonly used in general-purpose digital systems.

Replacement Considerations

Compatible substitutes include SN74ACT04N and SN74ACT04PW, provided the package type matches the existing footprint. Verify electrical parameters such as propagation delay and output current capabilities to ensure functional equivalence in the target application.
