74AHCT1G04DCKRE4

Overview

The SN74AHCT1G04DCKRE4 is a single inverter gate from the Texas Instruments 74AHCT logic family, housed in a SC-70-5 surface-mount package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports TTL-compatible input thresholds. The device features low static power consumption and high noise immunity typical of CMOS technology. Key electrical parameters include a propagation delay of 7.9 ns at 5 V with 50 pF load, output drive currents of ±8 mA, and an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides single-channel inversion functionality for digital signal processing applications.
• Ensures compatibility with both CMOS and TTL logic families through AHCT input threshold design.
• Delivers robust performance with high noise immunity and low quiescent current consumption.

Applications

• General-purpose digital logic signal inversion
• Clock signal buffering and conditioning
• Interface circuits between mixed-voltage logic domains

Procurement Notes

Verify the complete part number including the RE4 suffix to ensure compliance with specific environmental or manufacturing standards. Confirm that the SC-70-5 package dimensions align with your PCB footprint requirements. Check for RoHS compliance status as indicated in official documentation before finalizing procurement specifications.

Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS output characteristics. The AHCT series is suitable for systems needing operation across a wide voltage range while maintaining standard TTL logic levels. Ensure the application does not exceed the maximum specified output current or junction temperature limits defined in the datasheet.

Part Context

This device belongs to the SN74AHCT1Gxx series of single-function gates designed for compact embedded systems. The AHCT variant specifically bridges the gap between older TTL designs and modern CMOS technologies by accepting TTL inputs. The DCKR package offers a small form factor ideal for space-constrained portable electronics and dense circuit board layouts.

Replacement Considerations

Direct functional substitutes within the same family include the SN74AHCT1G04DC and SN74AHCT1G04DBVR. Verify pinout compatibility and package type (SC-70-5 vs SOT-23-5) when considering alternative packages. Cross-reference with SN74AHC1G04 variants if TTL input compatibility is not strictly required.
