Additional Details
The TC74VCX162721 features twenty D-type flip-flops with a common clock (CLK) and output enable (OE) input. When OE is low, the outputs are enabled; when OE is high, the outputs are in the high-impedance state. Data is clocked into the flip-flops on the rising edge of the clock signal. The device is designed with an output impedance control circuit to minimize reflections and signal distortion in high-speed applications. The operating temperature range is -40°C to +85°C, making it suitable for a wide range of environments. The propagation delay is typically 3.0 ns at 3.3V, ensuring fast and efficient data transfer. The device supports a wide operating temperature, and it is RoHS compliant. The 3-state outputs allow for easy interfacing with shared buses and memory systems.
