SN74AHC1G00DCKRE4

Overview

The SN74AHC1G00DCKRE4 is a single 2-input NAND gate from the Texas Instruments SN74AHC1G00 series. It operates within a supply voltage range of 2 V to 5.5 V and features low dynamic power consumption. The device provides symmetric output drive capabilities with both high and low level output currents rated at 8 mA. Propagation delay is specified at 6.5 ns. It is housed in a SC-70 (SOT-353) 5-pin surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Single-function logic gate providing one independent 2-input NAND operation
• Compatible with standard CMOS logic families through wide supply voltage operation
• Low static power consumption characteristic inherent to AHC technology
• Symmetric output drive strength for balanced signal transitions

Applications

• Portable battery-powered equipment requiring low power logic
• Consumer electronics utilizing 3.3 V or 5 V logic levels
• Automotive infotainment and control systems
• Industrial communication interface circuits

Procurement Notes

Verify the complete part number including the RE4 suffix to ensure compliance with specific environmental directives such as RoHS and halogen-free requirements. Confirm the SC-70 package variant matches the intended PCB footprint. Check current production status and lead times directly with authorized distributors, as availability may vary by region and volume.

Selection Notes

Select this component when a compact NAND gate is required for space-constrained designs. The AHC series offers faster switching speeds compared to standard HC devices while maintaining CMOS compatibility. Ensure the system voltage falls within the 2 V to 5.5 V range. Consider the SC-70 package size relative to available board real estate and thermal constraints during layout.

Part Context

This device belongs to the SN74AHC1Gxx family of ultra-small single-gate logic ICs. These components are designed to replace older discrete logic solutions in modern portable applications. The AHC technology combines the speed of ALVC with the compatibility of HC inputs. The DCK package denotes the specific SC-70 physical outline used for surface mounting.

Replacement Considerations

SN74AHCT1G00DCKRE4: Compatible if the system requires TTL-compatible input thresholds instead of CMOS thresholds. SN74LVC1G00DCKRE4: Suitable alternative offering higher drive current but different input threshold characteristics. Verify pinout compatibility and electrical specifications before substitution.
