SN74AHC1G08DCKRE4

Overview

The SN74AHC1G08DCKRE4 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 maximum propagation delay of 7 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 action to tolerate slow rise and fall times
• Provides low static power consumption with maximum ICC of 10 µA
• Ensures latch-up performance exceeding 250 mA per JESD 17 standards

Applications

• Consumer electronics
• Computer and computer peripheral equipment
• Embedded design and development
• Sensing and instrumentation
• HVAC systems

Procurement Notes

Verify the specific RE4 suffix against the manufacturer's official documentation to confirm packaging details, as suffixes often denote tape-and-reel specifications or regional compliance variations. Ensure the SC-70-5 footprint matches your PCB layout constraints. Cross-reference the RoHS status and lead-free composition requirements with your assembly specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact single AND gate is required for low-voltage digital logic applications. The AHC series offers faster switching speeds compared to standard HC devices while maintaining compatibility with 5 V and lower voltage domains. Consider the Schmitt trigger feature if the application involves noisy environments or signals with gradual transitions that require clean digital switching thresholds.

Part Context

This part belongs to the SN74AHC1G08 family of single-function gates manufactured by Texas Instruments. The AHC (Advanced High-Speed CMOS) technology combines the speed of AHCT logic with the wide voltage operation of LVC devices. The SC-70-5 package represents a small-outline transistor variant designed for space-constrained surface-mount applications in portable and high-density electronic designs.

Replacement Considerations

SN74AHC1G08DCKR is a compatible alternative within the same series offering identical logical functionality and electrical characteristics.
