What are the key features of SN74LVC3G06DCURE4?
- 3 independent open-drain inverter channels with 32 mA sink current for wired-OR bus and LED drive applications
- 50 pF rated load capacitance supports direct connection to standard CMOS and LVC logic inputs
- 1.65 V to 5.5 V LVC supply range enables mixed 1.8 V, 3.3 V, and 5 V level-translation designs
- RoHS compliant SSOP-8 package with open-drain outputs for I2C, SMBus, and open-collector bus interfaces
What is SN74LVC3G06DCURE4 used for?
The SN74LVC3G06DCURE4 is used for logic level inversion and open-drain bus interfacing in microcontroller and FPGA designs requiring wired-OR logic, I2C pull-up drive, and open-collector compatible signal conversion between 1.8 V, 3.3 V, and 5 V domains. Its 32 mA open-drain outputs can directly drive LEDs, optical isolator inputs, and relay coils in industrial control interfaces where an active-low signal with high sink capability is needed. The triple-inverter architecture also supports compact signal conditioning for 3 independent channels on a single 8-pin device, reducing BOM count in space-constrained embedded system designs.

Frequently Asked Questions
How do the open-drain outputs of the SN74LVC3G06DCURE4 enable wired-OR bus designs in I2C applications?
The SN74LVC3G06DCURE4 open-drain outputs can only actively pull the output line low (up to 32 mA sink current), relying on an external pull-up resistor to establish the high state — this is exactly the behavior required by I2C and SMBus where multiple devices share a common SDA or SCL line and any device can pull the bus low without bus contention. Three independent open-drain inverter channels allow a single 8-pin device to buffer and invert 3 I2C or open-collector signals simultaneously.
What supply voltage range does the SN74LVC3G06DCURE4 support for mixed-voltage level translation?
The SN74LVC3G06DCURE4 operates from 1.65 V to 5.5 V, enabling it to interface between modern 1.8 V microcontrollers and legacy 5 V peripherals in mixed-voltage board designs. An input from a 1.8 V CMOS output is recognized as a valid logic level, and the open-drain output with a 3.3 V or 5 V pull-up resistor translates the inverted signal to the higher voltage domain, accomplishing bidirectional-equivalent level translation across 3 independent channels.
What load capacitance and sink current does the SN74LVC3G06DCURE4 support, and what can each output directly drive?
Each output of the SN74LVC3G06DCURE4 is rated for 50 pF load capacitance and 32 mA maximum low-level sink current, which is sufficient to directly drive standard CMOS bus inputs, small indicator LEDs at up to 20 mA forward current, and optical isolator LED inputs at typical 10 mA to 20 mA operating current. The 32 mA sink capability also supports driving reset lines and interrupt inputs on microcontrollers without external transistors.
When is the SN74LVC3G06DCURE4 preferred over a push-pull inverter such as SN74LVC3G04 in a bus design?
The SN74LVC3G06DCURE4 is preferred over push-pull alternatives like SN74LVC3G04 when the output must share a common bus line with other open-drain devices, since a push-pull output would conflict with another device pulling the line low while the push-pull drives it high. The open-drain topology of the SN74LVC3G06DCURE4 avoids bus contention in wired-OR configurations, making it the correct choice for I2C, SMBus, and multi-master open-collector control lines at 3.3 V or 5 V.
