Additional Details

The TC74VCX2574FK typically operates within a supply voltage range of 1.65V to 5.5V, making it compatible with various logic levels. The propagation delay is usually in the nanosecond range, depending on the operating voltage and load conditions. The device is commonly available in surface-mount packages such as SSOP or TSSOP. The operating temperature range spans from -40°C to +85°C. The output enable (OE) pin, when low, enables the outputs, allowing data to be transmitted. When OE is high, the outputs are in a high-impedance state, effectively disconnecting the device from the bus. Data is clocked into the flip-flops on the positive-going edge of the clock signal.
