Working Principle

The SN74LV273ADWG4 is a quad-D flip-flop with four D-type flip-flops internally connected as shown in Figure 1. It has a single clock that triggers the data transfer from the D inputs to the Q outputs. When the clock is low, the data from the D inputs is stored in the flip-flops. When the clock is high, the data is transferred from the D inputs to the Q outputs. The D-type flip-flops are reset by the master reset signal applied to the reset input of the device. The data-enable signals must be at logic low for the flip-flops to be enabled.

The SN74LV273ADWG4 also has a power-on reset circuit. This circuit monitors the power supply and generates a Reset signal (RST) when the supply voltage exceeds a preset threshold. This ensures that the device returns to a known state after powering up.
