Texas Instruments CD40174BE CMOS Hex D-Type Flip-Flop DIP-16

The Texas Instruments CD40174BE is a high-reliability CMOS integrated circuit, specifically a Hex D-type Flip-Flop. This device integrates six identical 'D'-type flip-flops, each with independent data inputs, while sharing a common clock and clear line for synchronous operation. Data is reliably transferred to the Q outputs on the positive-going (rising) edge of the clock pulse, enabling precise control in sequential logic circuits. A low level applied to the common clear input simultaneously resets all six flip-flops, providing a master reset function.

Engineered for efficiency and stability, it features standardized, symmetrical output characteristics and is 100% tested for quiescent current at 20V. It boasts an exceptionally low maximum input current of just 1µA at 18V, making it an excellent choice for low-power designs. As a 'Green' product, it complies with environmental standards, free from hazardous substances as per the latest SVHC assessment.
