The ET74LVC1G07 is a single non-inverting buffer with an open-drain output, belonging to the 74LVC logic family. It operates from 1.65V to 5.5V, making it versatile for mixed-voltage applications. The open-drain output allows level shifting and wired-OR connections when used with an external pull-up resistor. It can sink up to 32mA, suitable for driving LEDs or relays. The device is available in a compact SOT-353 package and operates over -40°C to 125°C, ideal for industrial and automotive use.
- Open-Drain Output Flexibility: Enables level shifting and wired-OR logic configurations.
- Wide 1.65V to 5.5V Supply: Compatible with multiple logic levels, reducing design complexity.
- High 32mA Sink Current: Can drive LEDs, relays, and other loads directly.
- Extended Temperature Range: Reliable operation from -40°C to 125°C for harsh environments.
Level Shifting with Open-Drain
The open-drain output with pull-up resistor allows the ET74LVC1G07 to shift logic levels between different voltage domains, such as 3.3V to 5V or 1.8V to 3.3V, by choosing the appropriate pull-up voltage.
Wired-OR Bus Connections
Multiple open-drain outputs can be connected together to form a wired-OR configuration, commonly used in interrupt lines or I2C communication buses.
Driving High-Voltage Loads
The open-drain output can switch loads up to the pull-up voltage (e.g., 12V) while the IC itself operates at low voltage, enabling interface with higher-voltage peripherals.
LED and Relay Driving
The 32mA sink capability is sufficient to drive LEDs or small relays directly, with the open-drain configuration allowing the load to be connected to a higher supply.
Power Sequencing and Reset Circuits
Use the buffer to generate active-low reset signals or power-good indicators, where the open-drain output can be pulled up to the appropriate rail.
Industrial Sensor Interfacing
In industrial controls, the open-drain output can interface with PLC inputs or other logic systems, providing robust signal transmission over longer distances.
