Overview
The SN74AHC1G08DCK3 is a single 2-input positive-AND gate from Texas Instruments' AHC 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 delivers an output drive current of ±8 mA at 5 V and exhibits low quiescent current (ICC) of 10 µA maximum. Propagation delay is specified at 7.9 ns at 5 V with a 50 pF load. It is housed in a compact SC-70-5 surface-mount package, suitable for space-constrained digital logic applications.
Feature Summary
- Executes Boolean AND function Y=A·B in positive logic
- Schmitt-trigger inputs tolerate slow rise and fall times
- Low power consumption with 10 µA maximum ICC
- Robust latch-up performance exceeding 250 mA per JESD 17
Applications
- Barcode scanners
- Embedded PCs
- Field transmitters for temperature or pressure sensors
- Cable solutions
- E-books
Procurement Notes
Verify the specific suffix DCK3 corresponds to the SC-70-5 tape-and-reel packaging configuration. Confirm RoHS compliance and lead-free status as documented in the official datasheet. Ensure the operating temperature range matches system requirements, typically -40°C to +85°C or extended variants depending on the exact revision. Cross-reference the manufacturer part number against authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a single 2-input AND gate is required in a minimal footprint. The AHC series offers high-speed performance comparable to older HC families but with lower power dissipation. The wide supply voltage range supports both 3.3 V and 5 V logic systems. Verify input voltage levels align with the driving source, noting the high-level input threshold characteristics defined in the electrical specifications table.
Part Context
This device belongs to the SN74AHC1Gxx family of single-gate logic ICs designed for portable and battery-operated applications. The AHC technology combines the speed of advanced CMOS processes with low power consumption. The SC-70-5 package provides a small outline solution ideal for high-density PCB layouts. It serves as a fundamental building block for combinational logic circuits in consumer electronics and industrial control systems.
Replacement Considerations
The SN74AHC1G08DCKR is a direct pin-compatible alternative in the same SC-70-5 package. Other variants like SN74AHC1G08DBVR offer the same logical function in a SOT-23-5 package, requiring layout adjustment. Ensure replacement parts maintain identical voltage ranges and propagation delays for signal integrity.
