7473 Dual J-K Flip-Flop IC (DIP-14) | Pro Tronix

Product Description

The 7473 Dual J-K Flip-Flop IC is a classic TTL logic integrated circuit featuring two independent, master-slave J-K flip-flops with individual clear inputs. Designed for digital logic experimentation, sequential circuit building, and counter design, the 7473 triggers reliably on the negative-going transition of the clock pulse, offering precise state-toggle and data-latch performance for educational kits and custom logic projects.

⚠️ Logic & Power Tip: Ensure your VCC supply remains strictly within the standard TTL range of 4.75V to 5.25V DC (5V nominal). Exceeding 5.5V can permanently damage classic TTL logic chips. Always tie unused inputs to VCC or GND to prevent erratic switching.

Technical & Architectural Highlights

• Dual J-K Architecture: Two independent J-K flip-flops with separate clocks, clears, and complementary $Q$ and $\bar{Q}$ outputs in a single DIP-14 package.

• Master-Slave Design: Prevents race conditions by capturing input data during the high clock level and transferring data to the output on the falling edge.

• Direct Clear Input: Asynchronous clear function allows instant resetting of the flip-flop state regardless of clock status.

• Standard TTL Compatibility: Direct logic-level compatibility with standard 7400-series TTL and microcontroller 5V GPIO pins.
