The 74LCX07FT from Toshiba is a hex non-inverting buffer with open-drain outputs. It operates from 1.65V to 5.5V, making it suitable for low-voltage and mixed-voltage systems. The open-drain outputs allow wired-OR connections and level shifting to higher voltages via external pull-up resistors. Each output can sink 32mA, enabling direct drive of LEDs or relays. The 14-TSSOP package is compact for space-constrained designs. It operates from -40°C to 85°C, suitable for commercial and industrial applications.
- Open-Drain Outputs: Enables wired-OR logic and level shifting to higher voltages.
- Wide 1.65V to 5.5V Supply: Compatible with 1.8V, 2.5V, 3.3V, and 5V systems.
- High Sink Current (32mA): Drives LEDs, relays, and other loads directly.
- Hex Configuration: Six independent buffers in one package, saving board space.
Wired-OR Bus Connections
Open-drain outputs allow multiple 74LCX07FT buffers to be connected to a single pull-up resistor, enabling wired-OR logic for interrupt lines or shared buses.
Level Shifting to Higher Voltages
With open-drain outputs, the pull-up resistor can be connected to a higher voltage (e.g., 5V or 12V), allowing the 3.3V buffer to drive higher-voltage loads.
I2C and SMBus Interfacing
The open-drain outputs are perfect for I2C/SMBus lines, which require open-drain drivers. The 74LCX07FT buffers and isolates bus segments.
Driving LEDs with External Supply
Connect the open-drain output to an LED with a pull-up to a suitable voltage. The 32mA sink current drives LEDs directly without additional transistors.
Power Sequencing Control
Use open-drain outputs to control power supply enable pins. The pull-up ensures a defined high level when the buffer is off, preventing glitches.
Industrial Sensor Multiplexing
In industrial systems, open-drain outputs allow multiple sensors to share a single ADC input via wired-OR, reducing I/O requirements.
