                                                MM74HC273WMX Overview
It is packaged in the way of 20-SOIC (0.295, 7.50mm Width). D flip flop is included in the Tape & Reel (TR)package. The output it is configured with uses Non-Inverted. The trigger it is configured with uses Positive Edge. Surface Mountmounts this electrical part. With a supply voltage of 2V~6V volts, it operates. -40°C~85°C TAis the operating temperature. This electronic flip flop is of type D-Type. FPGAs belonging to the 74HCseries contain this type of chip. You should not exceed 78MHzin the output frequency of the device. A total of 1elements are contained within it. In 20terminations, a transmission line is terminated with a JK flip flop that matches its characteristic impedance. D latch belongs to the 74HC273 family. An input voltage of 4.5Vpowers the D latch. Its input capacitance is 7pFfarads. This D flip flop belongs to the family of HC/UH. Electronic part Surface Mountis mounted in the way. There are 20pins on it. Its clock edge trigger type is Positive Edge. This part is included in FF/Latches. There are 8bits in its design. Vsup reaches its maximum value at 6V. Keeping the supply voltage (Vsup) above 2V is necessary for normal operation. Due to its reliability, this T flip flop is well suited for TAPE AND REEL. In order for the device to operate, it requires 2/6V power supplies. It consumes 8μA  current. There are 8 channels available.
