Product Description

The 74HCT175 features four edge-triggered D-type flip-flops with individual D inputs and Q and Q̅ outputs. The common clock (CP) and master reset (MR̅) inputs load and reset all flip-flops simultaneously. The reset is an active LOW input and when applied, will set all outputs to LOW, regardless of the state of the clock input or the D inputs. The flip-flops transition on the rising edge of the clock input. The device's ability to interface directly with TTL levels makes it highly valuable for mixed-technology environments.

With its robust design and high functionality, the NXP 74HCT175 is an excellent choice for designers looking for a reliable flip-flop component that delivers consistent performance and integrates seamlessly with existing TTL-based systems.
