SN74ALS1004DR

Overview

The SN74ALS1004DR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN54/74ALS series. It features six independent inverters with single inputs and non-inverting outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 14-SOIC package. It exhibits a maximum propagation delay of 7 ns at 5 V with a 50 pF load, ensuring high-speed signal inversion capabilities for digital logic applications.

Feature Summary

• Provides six independent inverting channels for signal processing
• Operates reliably within standard 5 V logic supply ranges
• Delivers fast switching performance suitable for high-frequency circuits

Applications

• Digital signal inversion in logic circuits
• Clock signal conditioning and buffering
• General-purpose logic gate implementation

Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 14-SOIC footprint matches the target PCB design constraints. Ensure compatibility with the intended operating temperature range of 0°C to +70°C for industrial or commercial environments before finalizing procurement specifications.

Selection Notes

Select this component when multiple independent inverting functions are required within a single package to minimize board space. Consider its ALS technology characteristics for balanced speed and power consumption compared to standard TTL alternatives. Evaluate the 14-SOIC package dimensions against available layout area and thermal dissipation requirements for the specific application environment.

Part Context

This part belongs to the Texas Instruments SN54/74ALS family, which utilizes Advanced Low-Power Schottky technology. This series offers improved speed-power product over previous generations while maintaining pinout compatibility with standard 74-series logic devices. The SN74ALS1004 variant specifically provides hex inverter functionality, serving as a fundamental building block for complex digital systems requiring signal phase reversal.

Replacement Considerations

Compatible substitutes include the SN74ALS1004D (tube packaging) and SN74ALS1004DE4 (lead-free variant). Verify functional equivalence and package compatibility before substitution.
