Overview
The SN74AHC1G08DCKR-NG is a single 2-input positive AND gate from the Texas Instruments AHC logic series. It operates within a supply voltage range of 2 V to 5.5 V and utilizes SC-70 (SOT-553) surface-mount packaging with five pins. The device features low static current consumption of 10 µA maximum and provides output drive currents of ±8 mA at 5 V. Propagation delays are specified as 7.9 ns at 5 V and 12.3 ns at 3.3 V under a 50 pF load condition, supporting operation across an industrial temperature range of -40 °C to +85 °C.
Feature Summary
- Executes Boolean AND functions for digital signal processing in single-channel configurations
- Provides robust latch-up protection exceeding 250 mA per JESD 17 standards
- Incorporates ESD protection capabilities compliant with JESD 22 specifications
Applications
- Consumer electronics circuit design
- Computer peripheral interface logic
- Embedded system development boards
- Sensor and instrumentation signal conditioning
Procurement Notes
Verify the specific 'NG' suffix designation against official Texas Instruments documentation to confirm its exact meaning regarding material composition or manufacturing variant. Ensure compatibility with standard SC-70 footprint requirements during procurement planning. Cross-reference datasheet revisions to validate electrical parameters against current production batches.
Selection Notes
Select this component when a compact single-gate solution is required for 2V to 5.5V logic systems. The AHC series offers speed-performance balance suitable for general-purpose applications. Verify that the SC-70 package dimensions fit the target PCB layout constraints. Confirm input/output voltage levels match the connected logic family requirements.
Part Context
This part belongs to the SN74AHC1G08 family of single-function gates manufactured by Texas Instruments. It serves as a fundamental building block for digital logic circuits requiring a two-input AND function. The AHC series is designed to bridge performance gaps between older HC and newer HCT technologies, offering CMOS compatibility with improved switching speeds.
Replacement Considerations
Compatible alternatives include SN74AHC1G08DCKR and SN74AHC1G08DRLR. Automotive-grade variants such as SN74AHC1G08QDCKRQ1 offer extended temperature ranges and qualification standards. Verify pinout and electrical characteristics before substituting.
