The item is packaged in 56-TFSOP (0.240, 6.10mm Width)cases. D flip flop is included in the Tape & Reel (TR)package. As configured, the output uses Tri-State, Non-Inverted. It is configured with a trigger that uses a value of Positive Edge. There is an electrical part that is mounted in the way of Surface Mount. A voltage of 2.3V~2.7V 3V~3.6Vis required for its operation. It is at -40°C~85°C TAdegrees Celsius that the system is operating. This D latch has the type D-Type. It is a type of FPGA belonging to the 74ALVCH series. In order for it to function properly, its output frequency should not exceed 350MHz. In total, it contains 2 elements. During its operation, it consumes 40μA quiescent energy. D latch belongs to the 74ALVCH16821 family. The input capacitance of this T flip flop is 5pF farads, which is defined as the capacitance between the input terminals of an op amp with either input grounded.
