• Output enabling/disabling
• Multiplexing

Features:

• Dual Buffer: Contains two independent buffer gates in a single package.
• 3-State Output: Allows the output to be high, low, or high-impedance (disabled).
• Low Power Consumption: Minimizes energy usage, suitable for battery-powered devices.
• Wide Operating Voltage Range: Operates over a broad voltage range, offering flexibility in various systems.
• Small Package: Compact package design enables efficient use of board space.

Benefits:

• Improved Bus Driving: Provides increased current drive for reliable data transmission.
• Data Isolation: 3-state outputs allow for isolating sections of a circuit when not in use.
• Reduced Power Consumption: Low power operation extends battery life in portable applications.
• Versatile Application: Wide voltage range makes it suitable for diverse systems and configurations.
• Space-Saving Design: Small package allows for integration in compact electronic devices.

The TC7WZ125FK features two independent buffer gates, each with a 3-state output controlled by an enable input. When the enable input is high, the buffer operates normally, passing the input signal to the output. When the enable input is low, the output is set to a high-impedance state, effectively disconnecting the buffer from the bus. It operates over a voltage range of 1.65V to 5.5V, making it compatible with various digital systems. The device is available in a small package, such as a FSV package, contributing to its compact size. The propagation delay is typically in the nanosecond range.

The TC7WZ125FK is commonly used for bus driving, providing increased current drive to ensure reliable data transmission across a bus. The 3-state output allows for data isolation, where sections of a circuit can be disconnected when not in use to prevent interference or reduce power consumption. This is particularly useful in memory addressing applications, where multiple memory chips share the same address bus. The enable input can be used to select which memory chip is active at any given time.
