Key Features

The 74HCT74D-653 from Nexperia is a dual positive edge-triggered D-type flip-flop featuring individual data (nD), clock (nCP), set (nSD), and reset (nRD) inputs, along with complementary outputs (nQ and nQ̅). Data at the nD input that meets the setup and hold time requirements on the LOW-to-HIGH clock transition is stored in the flip-flop and appears at the nQ output. Schmitt-trigger action on the clock input enhances tolerance to slower clock rise and fall times. Inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages above 40. The device operates within a supply voltage range of 4.5 V to 5.5 V and is capable of clock frequencies up to 59 MHz. With a maximum propagation delay of 15 ns at 5 V and a 50 pF load, it ensures swift data processing.

The 74HCT74D,653 is designed to operate reliably across a temperature range of -40°C to +125°C and is housed in a compact 14-SOIC package, making it suitable for high-density surface-mount applications.

Applications

Data storage and transfer in digital systems.
Frequency division and counting in timing applications.
State machine implementation in control systems.
Debouncing mechanical switches in input interfaces.
Synchronization of asynchronous signals in communication systems.

Product Overview

Nexperia’s 74HCT74D,653 is engineered for applications requiring reliable and fast D-type flip-flop operations. Its dual flip-flop configuration allows for efficient data storage and transfer, while the positive edge-triggered design ensures precise timing control. The inclusion of set and reset inputs provides flexibility in initializing or clearing the stored data. Schmitt-trigger action on the clock input enhances noise immunity, making it suitable for environments with slower signal transitions. Operating at TTL input levels and offering complementary outputs, this flip-flop integrates seamlessly into a wide range of digital circuits. Its low quiescent current and high-speed performance make it an ideal choice for power-sensitive and high-frequency applications.
