SN74AHCT1G04DCKT

Overview

The SN74AHCT1G04DCKT is a single Schmitt-trigger inverter from the Texas Instruments SN74AHCT1Gxx series. It operates within a supply voltage range of 2 V to 5.5 V and features CMOS/TTL-compatible inputs. The device utilizes an SC-70-5 surface-mount package and supports an operating temperature range from -40°C to +125°C. Key electrical characteristics include a propagation delay of 6.5 ns at 3.3 V, with output drive capabilities of 8 mA for both high and low states.

Feature Summary

• Schmitt-trigger action provides noise filtering and hysteresis for clean signal transitions.
• CMOS and TTL logic level compatibility ensures interoperability with various digital systems.
• Wide supply voltage operation supports diverse power environments.

Applications

• Signal conditioning for noisy digital lines
• Pulse width modulation applications
• Oscillator circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with official Texas Instruments documentation to validate availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when input signal integrity requires hysteresis to prevent multiple triggering due to noise. The AHCT series is appropriate for systems interfacing between 3.3 V logic and legacy 5 V TTL devices. Consider the SC-70-5 package constraints regarding thermal dissipation and board space limitations during layout design.

Part Context

This device belongs to the SN74AHCT1Gxx family of single-function gates designed for ultra-low power and high-speed applications. The family offers compact packaging solutions suitable for portable electronics. The SN74AHCT1G04 specifically implements inverting logic with Schmitt-trigger inputs, distinguishing it from standard inverters lacking hysteresis.

Replacement Considerations

SN74AHC1G04DCKT: Offers similar functionality but lacks Schmitt-trigger inputs. SN74LVC1G04DCKT: Provides faster switching speeds but may require different voltage considerations. Verify pinout compatibility and electrical parameters before substitution.
