The TC7WG126FK is a high-speed CMOS dual bus buffer gate with 3-state outputs and inverting outputs, manufactured by Toshiba Semiconductor and Storage. This device is designed for applications requiring isolation or buffering of signals on a shared bus, while also inverting the signal. Its 3-state output allows for multiple devices to share the same bus lines, enabling efficient data transfer.

Applications

• Bus Buffering with Inversion: Isolating, inverting and driving signals on a shared bus.
• Memory Interfacing with Inversion: Enabling, inverting signals for memory devices on a memory bus.
• Data Multiplexing with Inversion: Selecting and inverting data from multiple sources to a single destination.
• Address Decoding with Inversion: Enabling and inverting signals for specific memory or peripheral devices based on address signals.
• Portable Electronics: Suitable for battery-powered devices due to its low power consumption.

Features

• Dual Bus Buffer Gate with Inverting Outputs: Contains two independent bus buffer gates with inverting outputs in a single package.

Additional Details

The TC7WG126FK is housed in an ultra-small leadless package (US8 package), which is designed for high-density surface mounting. The device operates over a wide temperature range, making it suitable for a variety of environments. The supply voltage range typically spans from 1.65V to 5.5V, offering flexibility in system design.

The output enable (OE) input controls the 3-state output, allowing the device to be enabled or disabled. When disabled, the output is in a high-impedance state, effectively disconnecting the device from the bus. This allows multiple devices to share the same bus lines without contention. Furthermore, the output signal is inverted relative to the input signal. Complies with industry standards for RoHS and lead-free manufacturing.
