Functional Features

The SN74HCT374DBR is a D-type flip-flop with 3-state outputs. It has eight data inputs (D0-D7) and eight corresponding flip-flop outputs (Q0-Q7). The flip-flops are clocked by the CP input, and the outputs can be enabled or disabled using the OE input. The MR input allows for a master reset of all flip-flops.

Advantages and Disadvantages

Advantages: - High-speed operation - CMOS compatible inputs - 3-state outputs allow for bus sharing

Disadvantages: - Limited operating frequency compared to some other flip-flops - Requires external clock signal for proper operation

Working Principles

The SN74HCT374DBR operates based on the principles of D-type flip-flops. The data inputs (D0-D7) are latched into their corresponding flip-flops when a clock pulse (CP) is applied. The outputs (Q0-Q7) reflect the state of the inputs at the time of the clock pulse. The outputs can be enabled or disabled using the output enable (OE) input. The master reset (MR) input resets all flip-flops to a known state.
