What are the key features of CD74HC109M96?
- Dual positive-edge-triggered J-K flip-flops with independent asynchronous set and reset for full state control
- HC CMOS family operating from 2 V to 6 V supply at up to 20 MHz toggle frequency
- Complementary Q and Q-bar outputs per element enabling direct T-type, divide-by-2, or latch implementations
- Tape-and-reel (M96) 16-pin SOIC packaging optimised for high-volume automated SMT assembly
What is CD74HC109M96 used for?
The CD74HC109M96 is used in synchronous sequential circuits, frequency dividers, and state machines in microcontroller-based embedded designs operating at 3.3 V or 5 V. Its independent set and reset pins allow direct initialization of system state at power-on without extra combinational logic, reducing total component count. It is also used in data synchronization and handshake circuits in communication interfaces where edge-triggered sampling of asynchronous signals is required.

Frequently Asked Questions
How does CD74HC109M96 differ from a standard D flip-flop in state machine design?
Unlike a D flip-flop that samples only the D input on each clock edge, the J-K flip-flop in CD74HC109M96 supports four distinct input states: hold, set, reset, and toggle. This allows a single device to implement shift registers, counters, and toggle stages without external NAND or inverter gates, reducing the design to fewer ICs for state machines requiring more than 2 states.
What is the maximum clock frequency of CD74HC109M96 at 3.3 V, and how does it compare to 5 V operation?
At 5 V supply with 50 pF load, CD74HC109M96 operates up to 20 MHz. At 3.3 V supply the maximum reliable clock frequency drops to approximately 8 MHz due to increased propagation delay in the HC-family process, so designers targeting frequencies between 10 MHz and 20 MHz must ensure the supply remains at or above 4.5 V.
Can CD74HC109M96 replace a CD74HC74 dual D flip-flop in an existing board design?
The two ICs are not pin-compatible since CD74HC109M96 has J and K-bar inputs instead of a single D input on each element. However, wiring J high and K-bar high on CD74HC109M96 configures it identically to a D flip-flop, making functional replacement possible in 16-pin SOIC footprints with minor rerouting of 2 signal pins per element.
What output drive current does CD74HC109M96 provide for driving resistive or capacitive loads?
Each output of CD74HC109M96 sinks up to 6 mA at the specified 5 V test condition with 50 pF load capacitance. This current level is sufficient to drive standard CMOS loads, 10-kohm pull-down resistors, or optocoupler LEDs with a series 470-ohm resistor at 3.3 V without requiring a separate buffer stage.
