Additional Details

The TC74VCX162827FT is specified for operation across the -40°C to +85°C temperature range, making it suitable for both commercial and industrial environments. The built-in bus hold circuitry maintains the last valid logic state when the input is left floating, preventing unwanted oscillations and ensuring stable operation. Its bi-directional capability and non-inverting data path facilitate efficient data transfer between different parts of a system. This device is an ideal solution for applications requiring high-speed, low-power, and reliable data communication.
