Functional Features

D-type positive-edge-triggered flip-flop with clear (CLR) and clock (CLK) inputs.
Six outputs (Q0-Q5) provide the stored data based on the input signals.
Clear input (CLR) resets all outputs to low state when active.
Clock input (CLK) triggers the flip-flop to capture and store the input data.
Outputs remain stable during the low-to-high transition of the clock signal.

Advantages

High-speed operation due to CMOS technology.
Wide supply voltage range allows compatibility with various systems.
Low power consumption.
Compact TSSOP-16 package saves board space.
Clear input provides easy reset functionality.

Disadvantages

Limited output current capacity.
Sensitivity to electrostatic discharge (ESD) requires proper handling precautions.
Not suitable for high-voltage applications.

Working Principles

The CD74HC174MT is a D-type positive-edge-triggered flip-flop. When the clock input (CLK) transitions from low to high, the flip-flop captures and stores the data present at the D0-D3 inputs. The stored data is then available at the Q0-Q5 outputs. The clear input (CLR) resets all outputs to a low state when active.
