Description
The MM74HC74AMX is a high-speed, dual D-type flip-flop utilizing advanced silicon-gate CMOS technology. It features two independent flip-flops in a single 14-pin package. Each flip-flop is fully edge-triggered and includes asynchronous active-LOW Preset (PRE) and Clear (CLR) inputs, allowing for flexible state initialization independent of the clock.
Data at the D-input is transferred to the Q-output on the rising edge of the clock (CP) pulse. Because of its high noise immunity and low power consumption, this device is a reliable choice for sequential logic applications, frequency division, and state-machine design in digital systems.
Note: Product images are for illustrative purposes only. Please refer to the official Fairchild (ON Semiconductor) datasheet for precise setup and hold time requirements, as well as propagation delay timings essential for high-speed synchronization tasks.
Features
- Dual Flip-Flop: Two independent D-type flip-flops in one package.
- Asynchronous Control: Dedicated active-LOW PRE (Preset) and CLR (Clear) inputs for each flip-flop.
- Edge-Triggered: Efficient data capture on the LOW-to-HIGH clock transition.
- CMOS Efficiency: Combines low power consumption with high noise immunity.
- Logic Compatibility: Compatible with standard HC-series CMOS logic levels.
- Package: SOIC-14 (SMD) for surface-mount assembly.
Benefits
- Versatile Initialization: Asynchronous inputs allow you to force the flip-flops into a known state during system power-up or error recovery.
- High Logic Density: Dual configuration saves PCB space by providing two storage elements in a single footprint.
- Reliable Synchronization: Excellent edge-triggering characteristics ensure stable data transfer in clocked systems.
Applications
- State Machines: Storing state transitions in sequential control circuits.
- Frequency Division: Configuring the D-flip-flop for divide-by-2 timing operations.
- Data Buffering: Capturing and holding synchronous digital bits.
- Sequential Timing: Used in counters, shift registers, and pulse-sequencing logic.
