M74HC574B1R Overview

The flip flop is packaged in 20-DIP (0.300, 7.62mm). Package Tubeembeds it. As configured, the output uses Tri-State, Non-Inverted. In the configuration of the trigger, Positive Edgeis used. There is an electrical part that is mounted in the way of Through Hole. With a supply voltage of 2V~6V volts, it operates. It is operating at -55°C~125°C TA. Logic flip flops of this type are classified as D-Type. FPGAs belonging to the 74HCseries contain this type of chip. It should not exceed 90MHzin its output frequency. There is a consumption of 4μAof quiescent energy. Currently, there are 20 terminations. The M74HC57family includes it. The D flip flop is powered by a voltage of 4.5V . This JK flip flop has a 5pFfarad input capacitance. Devices in the HC/UHfamily are electronic devices. A part of the electronic system is mounted in the way of Through Hole. This board is designed with 20pins on it. An electronic part designed with 8bits is used in this application. As soon as 6Vis reached, Vsup reaches its maximum value. A normal operating voltage (Vsup) should remain above 2V. Its superior flexibility is attributed to its use of 8 circuits. It runs on 2/6Vvolts of power. A D flip flop with 2embedded ports is available. With a current output of 7.8mA , it offers maximum design flexibility. It has 3 output lines to operate.
