IC 7474 D FLIP FLOP in Pakistan

Product Specification

Functionality D FLIP FLOP Number of Pins 14 Ic Pin 14 This IC features two independent positive-edge-triggered D flip-flops, each with complementary outputs. The flip-flops capture the value on the D input at the moment of a positive clock edge—meaning the output updates precisely when the clock transitions from LOW to HIGH. Importantly, the triggering action depends on reaching a certain voltage threshold, not on the speed of the clock’s rising edge.

While the clock is either LOW or HIGH, you can safely change the data at the D input without affecting the output, provided the setup and hold time requirements are met. Additionally, the preset and clear inputs are asynchronous: applying a LOW signal to either will immediately set or reset the outputs, regardless of other input conditions. This makes the 7474 IC a reliable choice for applications requiring precise data storage and control.
