24-DIP (0.300, 7.62mm)is the way it is packaged. D flip flop is included in the Tubepackage. This output is configured with Tri-State, Non-Inverted. It is configured with a trigger that uses Positive Edge. Through Holeis positioned in the way of this electronic part. A voltage of 4.5V~5.5Vis required for its operation. Temperature is set to 0°C~70°C TA. This D latch has the type D-Type. It is a type of FPGA belonging to the 74F series. Its output frequency should not exceed 150MHz. A total of 1elements are present in it. As a result, it consumes 100mA quiescent current and is not affected by external forces. There have been 24 terminations. Power is supplied from a voltage of 5V volts. Electronic devices of this type belong to the F/FASTfamily. As soon as 5.5Vis reached, Vsup reaches its maximum value. Keeping the supply voltage (Vsup) above 4.5V is necessary for normal operation. The D flip flop is embedded with 2ports.
