STMicroelectronics 74ACT74TTR Dual D-Type Positive Edge-Triggered Flip-Flop

The 74ACT74TTR from STMicroelectronics is a high-speed CMOS Dual D-Type Positive Edge-Triggered Flip-Flop integrated circuit, designed to operate at exceptional levels of speed while maintaining low power consumption. This device is part of the 74ACT series, which is renowned for its advanced high-speed CMOS technology.

This flip-flop features individual data (D), clock (CLK), set (SD), and reset (RD) inputs for each flip-flop. Outputs include the complementary Q and Q-bar. The set and reset are asynchronous inputs, allowing for the flip-flop to be set or reset independently of the clock signal, offering greater flexibility in control applications. The edge-triggered design ensures that the flip-flop changes state only at the rising edge of the clock input, providing precise timing control.

The 74ACT74TTR is characterized for operation from -40°C to +85°C, making it suitable for industrial applications where temperature extremes may be encountered. It comes in a TSSOP-14 package, which is ideal for space-constrained applications. The device is also available in tape and reel packaging, making it suitable for automated assembly processes, and is designated by the TTR suffix in the part number.

Key features of the 74ACT74TTR include:

• High-speed operation: t<sub>PD = 8ns (max) at V<sub>CC = 5V
• Power-down protection provided on all inputs and outputs
• Low power dissipation: I<sub>CC = 4µA (max) at T<sub>A = 25°C
• Standardized, symmetrical output characteristics
• Guaranteed output skew
• Guaranteed multiple output skew
• Functional equivalent to the 74F74

Ideal for a variety of digital applications, the 74ACT74TTR is a versatile component for designers looking to incorporate reliable flip-flop functionality into their systems. Whether used in communication devices, computers, or complex control systems, this flip-flop offers the performance and reliability that professionals expect from STMicroelectronics products.
