Nexperia Flip Flop IC HC CMOS 14-Pin SO-14, JK Type, Negative Edge Triggered 74HC73D-Q100J

The Nexperia 74HC73D-Q100J is a dual JK type flip-flop IC from the HC logic family packaged in a 14-pin SO-14 surface mount format. It is designed for robust digital logic applications requiring negative edge triggered flip-flops with individual J, K, clock, and asynchronous reset inputs.

This CMOS device supports a wide power supply voltage from 2V up to 6V and features high noise immunity and low power consumption, making it suitable for automotive and industrial electronics environments. The clock input is equipped with Schmitt-trigger action to ensure reliable operation despite slower clock input rise and fall times, enhancing timing accuracy in noisy or slow-edge signal conditions.

The asynchronous reset (nR) overrides all inputs when driven low, forcing the nQ output low and its complement high. Clamp diodes on all inputs allow direct interfacing with voltage sources higher than VCC when current limiting resistors are used, protecting the device from overvoltage conditions.

Designed in accordance with AEC-Q100 Grade 1 standards, this device supports operating temperature ranges from -40°C to +125°C, fit for automotive applications where reliability under harsh conditions is mandatory. It also meets several JESD and JEDEC standards for electrostatic discharge and latch-up immunity, confirming its rugged industrial grade qualification.

The 14-pin SO-14 package allows compact surface mounting on printed circuit boards, suitable for automation, automotive control systems, electronic instrumentation, and other industrial control applications where precise JK flip-flop functionality is required.

This flip-flop IC is ideally deployed in automotive and industrial equipment due to its high reliability and temperature tolerance. Its low voltage and power profile make it energy efficient while maintaining strong logic performance.

Package and pins are optimized for automated assembly lines in electronics manufacturing. The device enables complex logic sequencing, counter functions, and register implementations in embedded controllers. Reliable reset capability and edge-triggered clocking simplify system design and signal integrity.
