Overview
The SN74AHC1G02DBVT is a single 2-input positive NOR gate manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and features Schmitt-trigger inputs for noise tolerance. The device provides an output drive capability of ±8mA at 5V and exhibits a maximum propagation delay of 6.5ns at 5V. It functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Implements Boolean function Y = A + B using positive logic
- Schmitt trigger action on all inputs for slow signal transition tolerance
- Low static power consumption with maximum ICC of 10µA
Applications
- Automotive body control modules (BCM)
- Portable consumer electronics
- Industrial process control systems
- Computing and peripheral equipment
Procurement Notes
Verify the specific package marking and date code against the manufacturer's latest datasheet revision. Confirm RoHS compliance status and lead finish specifications, as these attributes may vary based on manufacturing lot and regional regulatory requirements. Ensure the ordering part number matches the required suffix for tape-and-reel or cut-tape packaging configurations.
Selection Notes
Select this component when a compact single-channel NOR gate is required for low-power digital logic applications. The SOT-23-5 package offers space efficiency for high-density PCB layouts. Consider the Schmitt trigger input characteristic if the application involves signals with slow rise or fall times that require clean switching thresholds.
Part Context
This device belongs to the SN74AHC1G series of single-gate logic ICs. It shares the same logical functionality as the SN74AHC1G02 but utilizes the DBVT package variant. The series is designed for general-purpose digital applications requiring low power consumption and high speed in small form factors.
Replacement Considerations
Direct functional equivalents include the SN74AHC1G02DCKR and SN74AHC1G02DBVR. Verify pinout compatibility and package dimensions before substitution. Alternative packages such as DCK (SC-70) offer different footprint requirements while maintaining identical electrical characteristics.
