STMicroelectronics 74ACT174MTR Hex D-Type Flip-Flop

The 74ACT174MTR from STMicroelectronics is a high-speed CMOS Hex D-Type flip-flop integrated circuit, designed to deliver the functionality of six individual D-type flip-flops in a single package. This advanced technology device is optimized for use in a wide variety of digital applications, including data storage, data transfer, and signal processing.

Each flip-flop has a dedicated D (data) input and a Q (output) with its complement Q̅. The flip-flops are positive-edge triggered, meaning that the logic state at the D input is transferred to the Q output on the rising edge of the clock pulse. This feature allows for precise synchronization of data within your digital system. The 74ACT174MTR also includes a direct clear input, which when made high, immediately sets the output to low, thus providing an efficient way to reset the system during operation.

The device is characterized for operation from -40°C to +85°C, ensuring reliable performance across a broad range of environmental conditions. Its robustness and high-speed operation make it suitable for implementing buffer registers, shift registers, and state machines.

Key features of the 74ACT174MTR include:

• High-speed operation: t_PD = 8.5 ns (max) at V_CC = 5V
• Power-down protection is provided on all inputs and outputs
• Low power dissipation: I_CC = 4 µA (max) at T_A = 25°C
• Standardized, symmetrical output characteristics
• Guaranteed output skew to maintain signal integrity
• Multiple package options: Available in SOIC, TSSOP, and other surface-mount packages

With its combination of high-speed, low power consumption, and robust design, the STMicroelectronics 74ACT174MTR is an excellent choice for designers looking to implement efficient and reliable digital logic systems. Whether you're working on data storage solutions, communication protocols, or complex digital signal processing, this flip-flop IC can serve as a fundamental building block in your electronic designs.
