The SN74LVC1G07DCKR from Texas Instruments is a single buffer/driver with an open-drain output in an ultra-compact 5-pin SC-70 (SOT-353) package. The open-drain output configuration makes this device ideal for I2C and SMBus level translation, wired-OR bus interfaces, and logic level conversion between different voltage domains. When the input is high, the output NMOS transistor turns on and pulls the output low (sinking up to 24mA); when the input is low, the output transistor is off and the output floats, allowing an external pull-up resistor to pull the line to any voltage up to 5.5V, independent of the device VCC. This enables bidirectional voltage translation on I2C buses where a 3.3V or 1.8V MCU communicates with 5V peripherals. The device operates from 1.65V to 5.5V supply, and the input pins are overvoltage tolerant to 5.5V regardless of VCC, allowing the device to accept 5V signals even when powered at 1.8V. The 3.6ns typical propagation delay at 3.3V supports high-speed I2C (FM+ at 1MHz) and other fast open-drain protocols. The tiny SC-70 package (2.0 x 1.25mm) is ideal for space-constrained designs where only a single open-drain buffer is needed. The device is fully specified from -40 to +125C, suitable for industrial and automotive applications.

The SN74LVC1G07DCKR operates as a single open-drain buffer. Key operating principles include: (1) Open-Drain Output – the output stage consists of a single NMOS transistor between the output pin and GND; when the input is HIGH, the NMOS turns on and the output pulls LOW (sinks current); when the input is LOW, the NMOS turns off and the output is high-impedance; an external pull-up resistor is required to establish the HIGH logic level; (2) Level Translation – because the output only pulls LOW and the pull-up resistor can connect to any voltage up to 5.5V, the device can translate between different voltage domains; for example, a 3.3V MCU GPIO drives the input, and the output pull-up connects to 5V, creating a 3.3V-to-5V open-drain level shifter; (3) Wired-OR – multiple open-drain outputs can share the same pull-up resistor; if any output pulls LOW, the bus is LOW; all outputs must be OFF for the bus to be HIGH; this is the basis of I2C/SMBus communication; (4) Overvoltage Tolerant Inputs – the input stage can accept voltages up to 5.5V even when VCC is as low as 1.65V, thanks to a clamping structure that prevents the input voltage from exceeding the internal circuitry limits.

  • LED indicator: drive LED cathode to GND through open-drain output at 10-20mA
  • Logic inversion with pull-up: open-drain output with pull-up to different voltage creates level-shifted inverted signal
