The TC7WG125FK is a high-speed CMOS dual bus buffer gate with 3-state outputs, manufactured by Toshiba Semiconductor and Storage. This device is designed for applications requiring isolation or buffering of signals on a shared bus. Its 3-state output allows for multiple devices to share the same bus lines, enabling efficient data transfer.

Applications

• Bus Buffering: Isolating and driving signals on a shared bus.
• Memory Interfacing: Enabling and disabling memory devices on a memory bus.
• Data Multiplexing: Selecting data from multiple sources to a single destination.
• Address Decoding: Enabling 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: Contains two independent bus buffer gates in a single package.
• 3-State Outputs: Allows the output to be in a high, low, or high-impedance state.
• High-Speed Operation: Provides fast propagation delays for quick signal processing.
• Low Power Consumption: Minimizes power dissipation, making it suitable for battery-powered applications.
• Wide Operating Voltage Range: Supports a wide range of supply voltages.
• Small Package Size: Available in a compact package, saving valuable board space.
• CMOS Technology: Utilizes CMOS technology for low power consumption and high noise immunity.

Benefits

• Simplified Bus Design: Reduces bus loading and simplifies bus arbitration.
• Improved System Performance: High-speed operation ensures minimal signal degradation and maintains system performance.
• Extended Battery Life: Low power consumption contributes to longer battery life in portable devices.
• Reduced Board Space: Small package size allows for more compact and efficient designs.

Additional Details

The TC7WG125FK 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. Complies with industry standards for RoHS and lead-free manufacturing.
