Overview
The Texas Instruments SN74HC74N is a dual D-type positive-edge-triggered flip-flop integrated circuit. It is part of the HC series of logic devices and is designed to store and synchronize data in digital circuits. The IC features two independent flip-flops, each with a data (D) input, a clock (CLK) input, a clear (CLR) input, a preset (PRE) input, and complementary outputs (Q and Q’). This device is widely used in various digital circuit applications due to its wide operating voltage range, high-speed performance, and low power consumption.
