SN74LS175D

Flip Flops Overview

The SN74LS175D is a quad D-type flip-flop with positive-edge triggering, manufactured by Texas Instruments. It features independent clock inputs for each flip-flop and a common clear input that resets all outputs to a low state when activated. The device operates within a standard voltage range of 4.75V to 5.25V. It utilizes the LS-TTL logic family, providing high-speed operation with low power consumption. The package type is SOIC-16, suitable for surface-mount applications.
