Additional Details

The TC74AC377P consists of eight edge-triggered D-type flip-flops with individual D-inputs and a common clock (CLK) and clock enable (EN) input. The device stores the data present at the D-inputs on the positive-going edge of the clock pulse, provided the clock enable input is low. When the clock enable input is high, the clock signal is inhibited, and the flip-flops retain their previous state. The outputs (Q0-Q7) provide the stored data.

This device is available in a plastic Dual In-Line Package (DIP), making it easy to handle and install on printed circuit boards. The operating temperature range is typically -40°C to +85°C, making it suitable for a wide range of applications.
