概要
Description
- Inputs: D, CP (clock, rising edge), PRE (asynchronous preset), CLR (asynchronous clear)
- Outputs: Q and Q̅ (complement)
How it works:
- If PRE is low, Q is set to 1 regardless of D.
- If CLR is low, Q is cleared to 0 regardless of D.
- When PRE and CLR are both high, Q follows D on the rising edge of CP (positive-edge triggered).
Notes:
- PRE and CLR are typically active-low (inverted bubbles on schematic).
- If both PRE and CLR are low at the same time, the outputs are undefined.
- Supply voltage Vcc is commonly 2–6 V; characteristic timing (setup/hold, tpd) varies with Vcc and temperature.
- Package variants like AMX denote a specific 14-pin CMOS package (SOIC/TSSOP family).
Common uses: data storage, small registers, shift registers, timing circuits, and simple counters. Always consult the datasheet for exact pinout and timing specs.
Equivalent
Features
- Dual, positive-edge-triggered D-type flip-flops (two independent sections).
- Asynchronous preset (PRE) and clear (CLR) for each flip-flop (active LOW).
- Each flip-flop has D, CLK, PRE, CLR inputs; outputs Q and Q̄.
- Two independent clock inputs (one per flip-flop) for flexible timing.
- CMOS technology; wide supply range 2V to 6V; low power consumption.
- High-speed CMOS performance suitable for MHz-range operation (depends on Vcc).
- Industrial temperature range (typically -40°C to +125°C).
- Package variant MM74HC74AMX (14-pin) in AMX/SMT package formats.
Common uses: clocked storage, counters, toggling/dividing circuits, and shift-register-like applications.
Pinout
Function: Dual D-type, positive-edge-triggered flip-flop with asynchronous preset and clear. Each flip-flop has D, clock (CP), preset (PRE), clear (CLR) inputs and Q and Q̅ outputs (two flip-flops per package).
Manufacturer
- What kind of company: A global semiconductor company that designs, manufactures, and sells energy‑efficient integrated circuits, discretes, sensors, and related semiconductor components for automotive, industrial, consumer, and communications markets.
Application
- Data storage and registers (parallel-in/parallel-out) in digital systems
- Timing and sequencing: state machines, counters, timing control logic
- Frequency division and clocking circuits (e.g., divide-by-2 using Q or Q̄)
- Shift registers and serial/parallel data handling
- Clock-domain data synchronization in simple systems (with proper handling of metastability and resets)
