What are the key features of SN74HC05DBRE4?
- 6 independent open-drain inverter channels in a single SOIC-14 package enable wired-AND bus configurations without external components
- HC/UH family CMOS logic supports wide supply voltage operation with low quiescent current consumption
- 4 mA open-drain output sink current allows direct interface with I2C pull-up lines and voltage level-shifting circuits
- 50 pF rated load capacitance maintains signal integrity across moderately capacitive PCB trace loads
What is SN74HC05DBRE4 used for?
SN74HC05DBRE4 is used in digital interface circuits that require open-drain inversion, such as I2C bus buffering, wired-OR logic, and level-shifting between 3.3 V and 5 V systems. The open-drain outputs allow multiple devices to share a common pulled-up bus line, making this hex inverter a practical choice for inter-board communication and interrupt aggregation circuits. It also serves as a general-purpose logic inversion stage in microcontroller-based designs where individual signal polarities need to be reversed.

Frequently Asked Questions
What output configuration does SN74HC05DBRE4 use and how does that enable level-shifting between different logic voltages?
SN74HC05DBRE4 uses open-drain outputs, meaning each inverter output can only pull low—the high state is defined by an external pull-up resistor connected to any supply voltage the designer chooses. This allows a 3.3 V-logic input signal to be inverted and pulled up to a 5 V rail through an external resistor, achieving bidirectional voltage level-shifting without an external level-translator IC. Maximum sink current is 4 mA, which sets the minimum pull-up resistor value for a given supply voltage.
How many inverter channels does SN74HC05DBRE4 contain, and what is the rated load capacitance per channel?
SN74HC05DBRE4 provides 6 independent single-input inverter channels in its SOIC-14 package, each rated for a maximum load capacitance of 50 pF. The 6-channel count means a single device can invert an entire 6-bit bus or serve 6 separate signal lines simultaneously, reducing part count in multi-signal inversion designs compared to using individual inverter buffers.
For an I2C bus expander design, how does SN74HC05DBRE4 compare to a dedicated I2C buffer IC?
SN74HC05DBRE4 is a simpler and lower-cost option than a dedicated I2C buffer when the designer only needs passive open-drain inversion along the bus lines. Each channel sinks up to 4 mA, sufficient to pull down a standard I2C line with a 4.7 kΩ pull-up at 3.3 V or 5 V. However, a dedicated I2C buffer provides built-in capacitance isolation, automatic direction detection, and level translation in one device, making it better suited for long bus runs or mixed-voltage multi-master topologies.
Which SOIC package variant does SN74HC05DBRE4 use and what are the key PCB layout implications?
SN74HC05DBRE4 is housed in an SOIC-14 package (JEDEC MS-012) with a 1.27 mm lead pitch and a body width of 3.9 mm. This footprint is standard across HC logic families, so existing SOIC-14 pads designed for other hex logic ICs such as 74HC04 are pin-compatible with 74HC05 in most signal assignments. The narrow 3.9 mm body width allows dense placement alongside other SOIC logic in 0.1 inch-grid PCB designs.
