Supplier Device Package 14-VSSOP

The TC74LCX07FK is a hex non-inverting buffer from Toshiba, part of the 74LCX logic family. It operates from 1.65V to 5.5V, providing excellent flexibility for mixed-voltage applications. Each of its 6 channels has an open-drain output capable of sinking 32mA, enabling wired-OR logic and direct LED driving. The 14-pin VFSOP package is compact, saving valuable board space. With a temperature range of -40°C to 85°C, it is suitable for a wide variety of commercial and industrial applications. Typical uses include I2C bus buffering, level shifting, and signal conditioning.

  • 6 Channels in One Package: Reduces component count and board space.
  • Wide 1.65V to 5.5V Supply: Compatible with multiple logic families, simplifying design.
  • Open-Drain Outputs: Enable wired-OR connections and level shifting.
  • 32mA Sink Current: Drives LEDs and other loads directly.
  • Compact VFSOP Package: Ideal for space-constrained consumer electronics.

I2C Bus Buffering

Use the TC74LCX07FK to buffer I2C signals. Its open-drain outputs with 32mA sink capability allow multiple devices to share the bus while maintaining signal integrity.

Level Shifting for Mixed-Voltage Systems

With a wide supply range, this buffer can translate signals between 1.8V and 5V logic. Connect pull-up resistors to the target voltage rail to achieve seamless level shifting.

Driving Multiple LED Indicators

Each of the 6 channels can sink 32mA, making it possible to drive up to six LEDs directly from logic outputs, simplifying control panel designs.

Wired-OR Interrupt Lines

In microcontroller systems, connect multiple interrupt sources to a single line using open-drain outputs. Any device can pull the line low, triggering the processor.

Signal Conditioning in Consumer Electronics

In TVs, set-top boxes, and gaming consoles, this buffer cleans up signals between different ICs, ensuring reliable data transmission over PCB traces.

Industrial Sensor Arrays

Buffer multiple sensor outputs in industrial control systems. The -40°C to 85°C range ensures reliable operation in factory environments.
