                                                74AC574SC Overview
The item is packaged in 20-SOIC (0.295, 7.50mm Width)cases. Package Tubeembeds it. There is a Tri-State, Non-Invertedoutput configured with it. Positive Edgeis the trigger it is configured with. There is an electrical part that is mounted in the way of Surface Mount. A supply voltage of 2V~6V is required for operation. Temperature is set to -40°C~85°C TA. Logic flip flops of this type are classified as D-Type. In this case, it is a type of FPGA belonging to the 74AC series. Its output frequency should not exceed  153MHz Hz. There are 1  elements in it. As a result, it consumes 40μA of quiescent current without being affected by external factors. In 20terminations, a transmission line is terminated with a JK flip flop that matches its characteristic impedance. An input voltage of 3.3Vpowers the D latch. A JK flip flop with a 4.5pFfarad input capacitance is used here. In this case, the D flip flop belongs to the ACfamily. 6Vis the maximum supply voltage (Vsup). For normal operation, the supply voltage (Vsup) should be above 2V. A total of 2ports are embedded in the D flip flop. In addition, you can refer to the additinal BROADSIDE VERSION OF 374 of the D latch.
