Functional Features

• Octal Transparent Latch: The TC74LCX373FTELM can store and latch digital data on its inputs.
• 3-State Outputs: It provides three output states - high, low, and high impedance, allowing multiple devices to share a common bus.
• Low Voltage Operation: The IC operates at low voltage levels, making it suitable for battery-powered applications.
• Fast Switching Speed: The TC74LCX373FTELM has a maximum operating frequency of 100MHz, enabling high-speed data processing.

Advantages and Disadvantages

Advantages: - Low voltage operation reduces power consumption. - 3-state outputs allow for efficient bus sharing. - Fast switching speed enables high-speed data processing.

Disadvantages: - Limited number of inputs/outputs (8 in total). - Requires careful handling due to the small package size.

Working Principles

The TC74LCX373FTELM functions as an octal transparent latch. When the Output Enable (OE) pin is active (low), the data present on the input pins (D0-D7) is latched and stored. The stored data is then available on the output pins (Q0-Q7). When the OE pin is inactive (high), the outputs are in a high impedance state, allowing other devices to drive the bus.

Detailed Application Field Plans

The TC74LCX373FTELM is commonly used in various digital systems, including but not limited to: - Microcontrollers and microprocessors - Data storage systems - Communication equipment - Industrial automation - Automotive electronics
