Product Overview: 74AHCT74D from NXP Semiconductors

The 74AHCT74D is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). Manufactured by NXP Semiconductors, a global leader in smart connected solutions, this dual positive-edge triggered D-type flip-flop integrates cutting-edge technology to ensure reliable performance for a wide range of applications.

The 74AHCT74D is characterized by its high noise immunity and low power consumption, making it an excellent choice for interfacing with TTL levels. This device features two independent D-type flip-flops with individual clear and set inputs for each flip-flop. The outputs are buffered for best system performance. The set and reset are asynchronous active LOW inputs and operate independently of the clock input.

Key Features:

• Logic Type: Dual D-Type Flip-Flop
• Operating Voltage: 4.5V to 5.5V
• High-Speed: Typical tpd of 8ns
• Output Capability: Standard
• ICC Category: Flip-Flop

The device is equipped with a clock input (CP) and an output (Q) for each flip-flop. When the clock goes HIGH, the D input state is captured at the time of the rising edge and is transferred to the Q output. With a wide operating temperature range, the 74AHCT74D is suitable for industrial and commercial applications requiring a robust performance.

The 74AHCT74D comes in a 14-pin SOIC package, which is not only space-saving but also compatible with standard surface-mount manufacturing processes. The package is designed for optimized heat dissipation and long-term reliability, ensuring that the device can handle the demands of continuous operation in a variety of environments.

In summary, the 74AHCT74D from NXP Semiconductors is a versatile and reliable component for digital logic circuits requiring flip-flops. Its compatibility with LSTTL levels, coupled with low power consumption and high noise immunity, makes it a preferred choice for designers looking to create efficient and dependable systems.
