The TC7WH126FK(T5RSOYF) is a high-speed CMOS quad buffer with non-inverting 3-state outputs from Toshiba Semiconductor and Storage. This device is part of the TC7WH series, known for its high-speed performance and low power consumption. The 3-state outputs allow for easy connection to bus-oriented systems where multiple devices share a common data line.

Applications

• Memory interface
• Bus transceivers
• Data multiplexing
• Address drivers
• General-purpose logic

Features

• High-speed operation: Typical propagation delay of 4.5 ns (at VCC = 5V).
• Low power consumption: ICC = 2μA (max) at VCC = 5.5V.
• Wide operating voltage range: 2V to 5.5V.
• 3-state outputs: Allows direct connection to bus-oriented systems.
• Non-inverting outputs: Simplifies logic design.
• Small package: VSSOP8 (Very Small Shrink Outline Package).

Benefits

• Improved system performance due to fast switching speeds.
• Reduced power consumption, contributing to longer battery life in portable devices.
• Increased system flexibility due to wide operating voltage.
• Simplified bus interfacing with 3-state outputs.
• Smaller board space requirements due to compact VSSOP8 package.
• Enhanced signal integrity due to non-inverting design.

Additional Details

The TC7WH126FK operates over a wide temperature range, typically -40°C to 85°C, making it suitable for various industrial and consumer applications. The device's 3-state outputs are controlled by an output enable (OE) pin. When OE is low, the output is enabled, and the buffer passes the input signal to the output. When OE is high, the output is disabled and enters a high-impedance state, allowing other devices to drive the bus. This feature is crucial in applications where multiple devices share a common data line. The input and output pins are ESD protected, ensuring high reliability and robustness.
