SN74HC74N

The SN74HC74N is a high-performance, CMOS-based dual D-type positive-edge-triggered flip-flop with clear and preset functionalities. It belongs to the 74HC series of logic ICs, which are known for their high speed, low power consumption, and compatibility with TTL logic levels.

Key Features:

1. Dual Flip-Flop Configuration:
   • The SN74HC74N contains two independent D-type flip-flops, each triggered by the positive edge (rising edge) of the clock input.
2. Clear and Preset Functions:
   • Each flip-flop has a clear (CLR) and a preset (PR) input.
   • When the CLR input is active (low), the flip-flop is reset to a known state (Q = 0, Q’ = 1).
   • When the PR input is active (high), the flip-flop is set to the opposite state (Q = 1, Q’ = 0).
3. CMOS Technology:
   • The SN74HC74N is manufactured using advanced CMOS technology, which results in low power consumption and high noise immunity.
4. TTL-Compatible Logic Levels:
   • The IC operates with TTL-compatible logic levels, making it easy to interface with other TTL devices in digital circuits.
5. Wide Operating Voltage Range:
   • The SN74HC74N can operate within a wide voltage range of 2.0V to 6.0V, providing flexibility in different power supply environments.
6. High Speed and Low Propagation Delay:
   • The flip-flops have a maximum propagation delay of 37ns (typical), ensuring fast data processing in digital systems.
7. 14-Pin PDIP Package:
   • The IC is packaged in a 14-pin plastic dual-in-line package (PDIP), which is suitable for through-hole mounting on printed circuit boards.
8. Applications:
   • The SN74HC74N is widely used in various digital circuits, such as programmable logic controllers (PLCs), microprocessors, and microcontrollers.
   • It can be used to store and transmit binary information, build latch circuits, and create complex digital logic circuits such as flip-flop chains.

Summary:

The SN74HC74N is a versatile and reliable dual D-type flip-flop IC with clear and preset functionalities, CMOS technology, TTL-compatible logic levels, and a wide operating voltage range. Its high speed and low power consumption make it an ideal choice for use in digital systems requiring fast data processing and reliable timing control.
