7476 Dual JK Flip-Flop IC (DIP)

Overview — 7476 Dual JK Flip-Flop IC (DIP)

The 7476 Dual JK Flip-Flop IC (DIP) contains two independent JK bistable elements with asynchronous preset and clear inputs. Housed in a standard 14-pin Dual In-line Package, the IC is designed for reliable edge-triggered operation and easy integration into 74-series TTL logic systems. Each flip-flop supports set, reset, and toggle modes, making the device well suited for a wide range of sequential logic tasks.

Key Features

• Two independent JK flip-flops in a single 14-pin DIP
• Asynchronous preset (PR) and clear (CLR) inputs for immediate control
• Edge-triggered clock input for precise state changes
• Suitable for TTL-level systems and other 74-series ICs
• Compact through-hole package ideal for prototyping and PCB mounting

Applications

• Binary and decade counters
• Frequency division and toggle circuits
• Shift registers and data storage elements
• Sequential logic design and finite state machines
• Microcontroller interface circuits and digital automation

Design and Integration Tips

When using the 7476 Dual JK Flip-Flop IC, consider the following best practices:

• Observe proper power-supply decoupling (bypass capacitors) near VCC and GND to ensure stable TTL operation.
• Use pull-up or pull-down resistors as needed on asynchronous inputs to prevent undefined states.
• Ensure clean clock edges to avoid metastability and unintended toggling; Schmitt-trigger buffering can help.
• Verify logic-level compatibility when interfacing with other families or modern CMOS devices; level shifting may be required in mixed-signal designs.

Typical Circuit Examples

• Divide-by-2 frequency divider using toggle mode (J and K tied high)
• Binary counter stage when cascaded with additional flip-flops
• Controlled data latch within shift register chains

Package and Mounting

The 7476 is supplied in a 14-pin Dual In-line Package (DIP), making it compatible with solderless breadboards and standard PCBs. The through-hole form factor is convenient for prototyping and repair-friendly designs.
