M74HC74B1R Overview
The flip flop is packaged in 14-DIP (0.300, 7.62mm). The package Tubecontains it. T flip flop uses Differentialas its output configuration. JK flip flop uses Positive Edgeas the trigger. In this case, the electronic component is mounted in the way of Through Hole. It operates with a supply voltage of 2V~6V. Temperature is set to -55°C~125°C TA. There is D-Type type of electronic flip flop associated with this device. FPGAs belonging to the 74HCseries contain this type of chip. You should not exceed 67MHzin its output frequency. There is 2μA quiescent consumption. There are 14 terminations,The M74HC74family includes it. The power supply voltage is 4.5V. There is 5pF input capacitance for this T flip flop. This D flip flop belongs to the family of HC/UH. Electronic part Through Holeis mounted in the way. Basically, it is designed with a set of 14 pins. This device's clock edge trigger type is Positive Edge. This device has the base part number FF/Latches. As soon as Vsup reaches 6V, the maximum supply voltage is reached. The supply voltage (Vsup) should be maintained above 2V for normal operation. Despite its superior flexibility, it relies on 2 circuits to achieve it. With a current output of 5.2mA , it offers maximum design flexibility. The inputs used are 1.
