SN74AHC05DGVRG4 Texas Instruments Integrated Circuit (Small Outline Packages) In Stock
Texas Instruments SN74AHC05DGVRG4 is a hex inverter with open-drain outputs from the AHC/VHC logic family, integrating 6 independent single-input inverter gates in a 14-pin SOIC package. Each gate drives an 8 mA output low current into a 50 pF load with no push-pull high output, enabling wired-OR bus configurations and level translation. It targets digital logic signal conditioning, bus arbitration, and open-collector interface circuits in industrial, consumer, and communication designs.

Frequently Asked Questions
Why does the SN74AHC05DGVRG4 use open-drain outputs instead of standard push-pull, and what advantage does this provide?
Open-drain outputs have no internal pull-up transistor, so multiple devices can share a single bus line without contention. When any device pulls the line low at 8 mA, the bus reads low; when all devices release, an external pull-up resistor defines the high level. This wired-OR topology is essential for I2C buses, alarm lines, and multi-master arbitration circuits commonly found in embedded systems.
How many inverter gates are included in SN74AHC05DGVRG4, and how are they packaged?
The SN74AHC05DGVRG4 contains 6 independent single-input inverter gates, each with its own open-drain output, housed in a 14-pin SOIC package. Having 6 gates in one package reduces component count and board space compared to using 6 discrete transistors, and the SOIC footprint is compatible with standard pick-and-place assembly for high-volume PCB manufacturing.
Can SN74AHC05DGVRG4 perform logic level translation between 3.3 V and 5 V systems?
Yes, the open-drain architecture allows the SN74AHC05DGVRG4 to translate levels between 3.3 V and 5 V domains. A 5 V pull-up on the output lets a 3.3 V logic signal drive the input while the output swings to 5 V, bridging the voltage mismatch. The 8 mA low drive and 50 pF load rating ensure reliable switching at speeds up to approximately 80 MHz in typical PCB trace environments.
What is the maximum output low current per gate and how does it compare to standard HC-family inverters?
Each gate in the SN74AHC05DGVRG4 sinks up to 8 mA in the output low state, which is consistent with AHC-family specifications. Standard HC-family inverters with open-drain outputs typically sink only 4 mA, making AHC a better choice when driving lower-value pull-up resistors or multiple parallel loads in bus configurations where faster edge rates are needed.
