SN74ALS1004NSR

Overview

The SN74ALS1004NSR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN54/74ALS logic family. 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 wide operating temperature range from 0°C to +70°C. Key electrical characteristics include a propagation delay of 7 ns at 5 V with 50 pF load, low static current consumption of 3 mA maximum, and output drive capabilities of 15 mA high and 24 mA low.

Feature Summary

• Contains six independent single-input inverter circuits for signal inversion applications
• Utilizes Advanced Low-Power Schottky (ALS) bipolar technology for optimized speed-power performance
• Provides robust output drive capability suitable for interfacing with various logic loads

Applications

• General-purpose digital signal inversion in logic circuits
• Clock signal conditioning and buffering
• Level shifting between compatible logic families

Procurement Notes

Verify the specific suffix 'NSR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards as indicated by manufacturer documentation. Ensure the ordering part number matches the exact logic family and package dimensions specified in the official datasheet to avoid integration errors during procurement.

Selection Notes

Select this component when designing systems requiring hex inversion functionality within the ALS logic family specifications. Consider the 14-pin SOIC package constraints for PCB layout and thermal management. Evaluate the 7 ns propagation delay against system timing requirements to ensure adequate signal integrity. Verify compatibility with the 4.5 V to 5.5 V power supply rails available in the target application environment.

Part Context

This component is part of the extensive SN54/74ALS series produced by Texas Instruments, designed for high-speed digital applications. The ALS family offers improved performance over standard TTL while maintaining lower power consumption than earlier Schottky variants. The SN74ALS1004 specifically provides hex inverter functionality, serving as a fundamental building block for complex digital logic designs requiring signal phase reversal or buffering.

Replacement Considerations

Direct replacements may include SN74ALS1004DR or SN74ALS1004D depending on preferred packaging variations such as tube versus reel formats. Cross-family alternatives like SN74AS1004 offer similar functionality with potentially different electrical characteristics. Verify pinout compatibility and logical equivalence before substituting any alternative part numbers.
