CD74HCT174 Hex D-Type Flip-Flop

The CD74HCT174 from Texas Instruments is a high-speed, high-performance hex D-type flip-flop with a clear feature. This integrated circuit is part of the 74HCT family, which is well-regarded for its compatibility with TTL (Transistor-Transistor Logic) while operating at the higher speed of CMOS technology. The device is specifically designed to have the same switching characteristics as the 74LS family, which makes it a suitable replacement for LS types in high-speed applications.

The CD74HCT174 contains six flip-flops with single-rail outputs. Each flip-flop is individually triggered by a low-to-high transition of the clock (CP) input. The clear (CD) input, when taken low, sets all six of the flip-flop outputs low, regardless of the other inputs' states. This feature provides a convenient way to quickly reset the entire device back to a known startup state.

Key Features:

• Logic Type: Hex D-type flip-flop with clear
• Operating Voltage: Typically 5V, which is ideal for TTL compatibility
• High-Speed Performance: Provides faster operation than standard LS logic while maintaining the power efficiency of CMOS technology
• Output Drive Capability: Capable of driving 10 LS-TTL loads, which makes it suitable for interfacing with multiple devices within a circuit
• Temperature Range: Can operate over a wide temperature range, making it suitable for industrial applications

The CD74HCT174 is packaged in a variety of forms, including the standard DIP and SOIC packages, providing flexibility for both through-hole and surface-mount PCB designs. Its robustness and dependability make it a go-to choice for applications such as memory registers, counters, and control circuits.

Overall, the CD74HCT174 is a versatile component that combines the best of both TTL and CMOS technologies, offering designers a reliable and high-speed solution for digital logic circuits. Its ability to interface with TTL logic levels while providing the benefits of CMOS technology, such as lower power consumption, makes it an excellent choice for modern digital systems.
