74HC174D

Overview

The Toshiba 74HC174D is a high-speed CMOS hex D-type flip-flop fabricated with silicon gate C2MOS technology. It features six independent D-type flip-flops, each capable of storing one bit of data. The device operates on a single supply voltage ranging from 2V to 6V. It includes a common clock input and an active-low clear input for all flip-flops. The output type is non-inverting. The component is designed for surface-mount applications in a 16-pin SOIC package.
