Key Features
- Dual open-drain non-inverting buffer in LVC family operating from 1.65 V to 5.5 V, enabling direct I2C bus driving and voltage level translation from 1.8 V logic to 5 V systems with a single 6-pin SOT-23 device
- 24 mA open-drain sink current per channel with 50 pF rated load capacitance supports I2C Fast-mode Plus (Fm+) at 1 MHz and direct LED or opto-coupler drive without external transistors
- RoHS e4 lead-free tape-and-reel packaging and wide 1.65 V to 5.5 V supply range simplify integration into mixed-voltage embedded systems and IoT designs
Applications
SN74LVC2G07DBVRE4 is commonly used as an I2C bus buffer and voltage translator between 1.8 V microcontrollers and 5 V peripheral devices such as EEPROMs and sensor modules, leveraging its open-drain output and pull-up flexibility. Its 24 mA sink current per channel also enables direct opto-coupler LED drive in industrial isolation circuits without a discrete transistor. The dual-channel device suits compact embedded designs where two I2C clock or data lines need concurrent buffering from a 3.3 V or 5 V rail within a 6-pin SOT-23 footprint.

Frequently Asked Questions
How does the open-drain output of SN74LVC2G07DBVRE4 enable voltage level translation from 1.8 V to 5 V on an I2C bus?
With an open-drain output, SN74LVC2G07DBVRE4 pulls the I2C line low when active but relies on an external pull-up resistor tied to the target voltage—for example, a 4.7 kΩ resistor to 5 V. This allows a 1.8 V LVC logic input to control a 5 V I2C bus without any damage to the low-voltage input stage, since the output never drives a high voltage—it only sinks 24 mA maximum to ground. Two channels handle both SDA and SCL simultaneously, covering a complete I2C interface in a 6-pin SOT-23 package.
For an industrial I2C Fast-mode Plus design at 1 MHz, can SN74LVC2G07DBVRE4 meet the required bus capacitance and current specifications?
I2C Fast-mode Plus (Fm+) requires at least 20 mA sink current to drive buses with up to 4,000 pF capacitance within the 120 ns fall time requirement. SN74LVC2G07DBVRE4 provides 24 mA maximum open-drain sink current, exceeding the 20 mA minimum. With a 50 pF rated load capacitance per output and a 1 kΩ pull-up to 3.3 V, the pull-down transition meets Fm+ timing. For buses with capacitance above 400 pF, an external bus buffer stage is recommended to maintain signal integrity at 1 MHz.
When would two SN74LVC2G07DBVRE4 channels share a pull-up voltage different from the MCU supply in a sensor hub design?
In a sensor hub connecting a 1.8 V MCU to legacy 5 V sensors via I2C, each SN74LVC2G07DBVRE4 channel uses a 4.7 kΩ pull-up tied to 5 V while the MCU supply remains at 1.8 V. The open-drain outputs safely pull the 5 V I2C bus to ground from 1.8 V logic inputs without any current flowing back into the MCU's 1.8 V rail, since the output stage never sources current. This configuration eliminates a dedicated level-shifter IC by using the 2 buffered channels for SDA and SCL simultaneously in a 6-pin SOT-23 device.
How does the SN74LVC2G07DBVRE4 6-pin SOT-23 footprint reduce PCB space compared to a discrete transistor implementation for 2 open-drain outputs?
A discrete implementation of 2 open-drain outputs using 2 NMOS transistors requires at minimum 2 SOT-23-3 packages (each 2.9 mm × 1.6 mm) plus 2 gate resistors, totalling roughly 5 components and 25 mm² of PCB area. SN74LVC2G07DBVRE4 integrates both buffered open-drain channels in a single 6-pin SOT-23 package measuring 2.9 mm × 1.6 mm, cutting component count by 4 and board area by approximately 80%. The LVC logic input also adds hysteresis and ESD protection up to 2 kV HBM, which a bare NMOS transistor does not provide.
