SN74HC377N (74HC377) logic chip

The SN74HC377N is a high-speed CMOS octal D-type flip-flop with a clock enable input. Each flip-flop has independent data (D) inputs and share common clock (CLK) and output enable (OE) inputs. The device features eight positive-edge-triggered flip-flops with 3-state outputs, providing the capability to drive bus lines or buffer memory address registers. When OE is low, the output data is enabled; when OE is high, the outputs are in the high-impedance state.
