Pinout
The SN74AS8741DWR is a 20-pin integrated circuit. It is an octal D-type flip-flop with 3-state outputs, typically used for temporary data storage, data transfer, and interfacing between bus systems. Each of the eight flip-flops features individual D inputs and Q outputs. The device also includes an active-low enable (OE\) for controlling the output stage and an active-low clock input (CLK\) for synchronizing data storage. When the enable is low, the data on the D inputs is transferred to the Q outputs on the rising edge of the clock input. When the enable is high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit. This feature makes the SN74AS8741DWR useful in bus-oriented systems, where multiple devices can share the same data lines.
