Additional Details:

The TC74LCX374FK-ELK utilizes advanced CMOS technology to achieve a balance of speed and power efficiency. It features a propagation delay in the nanosecond range and a quiescent current in the microampere range. The device is designed to be compatible with TTL logic levels, allowing for easy integration into existing systems. The operating temperature range is typically -40°C to +85°C, making it suitable for a wide range of environments. The output enable (OE) input controls the 3-state outputs; when OE is high, the outputs are in a high-impedance state, and when OE is low, the outputs reflect the data stored in the flip-flops. This feature is crucial for implementing bus-oriented systems where multiple devices share a common bus.
