Overview
The SN74AHCT1G08DCKR is a single 2-input AND gate from the Texas Instruments SN74AHCT1G08 series. It operates within a supply voltage range of 4.5 V to 5.5 V and features Schmitt trigger inputs for noise tolerance. The device provides an output current of ±8 mA and exhibits a maximum propagation delay of 7.9 ns at 5 V with a 50 pF load. It is housed in a compact 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 using positive logic conventions.
- Incorporates Schmitt trigger input circuitry to accommodate slow rise and fall times.
- Delivers robust output drive capability suitable for interfacing with various digital loads.
Applications
- Consumer electronics signal processing
- Computer peripheral interface circuits
- Embedded system control logic
- Communication network data routing
Procurement Notes
Verify the specific suffix DCKR corresponds to the SC-70-5 package configuration during procurement. Confirm that the required supply voltage aligns strictly with the 4.5 V to 5.5 V operational window defined by the AHCT series specifications. Ensure compatibility with standard surface-mount assembly processes given the small outline package dimensions.
Selection Notes
Select this component when a single AND gate is required with TTL-compatible input thresholds but CMOS output characteristics. The AHCT series ensures compatibility with 5 V systems while offering lower power consumption compared to older logic families. Consider the SC-70-5 package for space-constrained designs requiring high-density PCB layouts.
Part Context
This part belongs to the SN74AHCT1G08 family, which integrates advanced CMOS technology with TTL-compatible inputs. The family includes variants such as SN74AHCT1G08DRLR and SN74AHCT1G08PWR, differing primarily in packaging and reel specifications. These devices are designed for general-purpose digital applications requiring reliable logic operations in 5 V environments.
Replacement Considerations
SN74AHCT1G08DRLR offers identical electrical performance in an SOT-553 package. SN74AHCT1G08PWR provides the same functionality in a TSSOP-5 package. Verify pinout compatibility and thermal requirements when substituting these alternatives.
