Overview
The SN74AHC1G08DCKTG4 is a single 2-input positive AND gate from the Texas Instruments SN74AHC1G08 series. It operates within a supply voltage range of 2 V to 5.5 V and features Schmitt trigger inputs for noise tolerance. The device provides an output drive current of ±8 mA at 5 V and exhibits a propagation delay of 12.3 ns at 3.3 V or 7.9 ns at 5 V. It is housed in a SC-70-5 surface-mount package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Executes Boolean AND logic functions with two inputs and one output
- Incorporates Schmitt trigger input characteristics to accommodate slow rise and fall times
- Delivers ±8 mA output drive capability across the specified voltage range
Applications
- Consumer electronics systems
- Computer and peripheral equipment interfaces
- Embedded design and development platforms
- Sensing and instrumentation circuits
- HVAC control networks
Procurement Notes
Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the SC-70-5 package marking and pinout alignment with the target PCB footprint. Ensure the voltage domain matches the 2 V to 5.5 V operational limits defined in the official datasheet specifications.
Selection Notes
Select this component when a compact single-gate solution is required for low-power digital logic applications. The AHC series offers faster switching speeds compared to standard HC devices while maintaining CMOS compatibility. Verify that the input signal levels are compatible with the Schmitt trigger thresholds for reliable operation under varying load conditions.
Part Context
This part belongs to the SN74AHC1G08 family of single-function gates manufactured by Texas Instruments. The series is designed for high-speed, low-power applications requiring minimal board space. The G4 suffix typically denotes environmental compliance attributes such as lead-free construction and adherence to specific manufacturing standards.
Replacement Considerations
SN74AHC1G08DCKT is a direct functional equivalent within the same series. SN74AHC1G08DBVTG4 serves as an alternative using the SOT-23-5 package. SN74LVC1G08DCKRE4 offers higher drive current but requires verification of voltage level compatibility.
