Overview
The SN74AHC1G09DBVR is a single-channel, two-input AND gate from the Texas Instruments SN74AHC1Gxx series. It operates within a supply voltage range of 2V to 5.5V and features an open-drain output configuration. The device provides a maximum low-level output current of 8mA and a high-level output current of -8mA. Propagation delay is specified at 7.5ns when operating at 5V with a 50pF load. It is housed in a surface-mount SOT-23-5 package and supports industrial temperature ranges.
Feature Summary
- Open-drain output architecture allows flexible interfacing with various logic families and bus systems.
- Wide supply voltage operation supports compatibility across 2V to 5.5V power domains.
- Single-gate design minimizes board space requirements through compact packaging.
Applications
- Bus-oriented connections requiring wired-AND functionality
- I2C and SMBus interface pull-up implementations
- Level translation between different voltage logic domains
Procurement Notes
Verify the specific suffix 'DBVR' corresponds to the SOT-23-5 package and tape-and-reel orientation. Confirm RoHS compliance status and REACH SVHC declarations against the latest manufacturer documentation. Ensure the open-drain characteristic aligns with system requirements for external pull-up resistor integration.
Selection Notes
Select this component when an open-drain AND gate is required for bus arbitration or level shifting. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS compatibility. Verify that the application circuit includes appropriate pull-up resistors due to the open-drain output structure.
Part Context
This part belongs to the SN74AHC1Gxx family of single-function gates designed for portable and battery-powered applications. The AHC series utilizes advanced silicon-gate technology to achieve high-speed performance with low power consumption. The DBVR suffix indicates the specific SOT-23-5 surface-mount package variant manufactured by Texas Instruments.
Replacement Considerations
Direct substitutes include Diodes Incorporated 74AHC1G09W5-7 and Nexperia 74AHC1G09GV,125. These alternatives share similar logical functions and pinouts but may differ in electrical characteristics such as propagation delay or output drive strength. Verify package compatibility and voltage specifications before substitution.
