The MC74AC74DR2G is a dual D-type positive edge triggered flip-flop with complementary outputs. This type of flip-flop is used in logic circuits and other applications where a reliable output is required. The device is based on the classic flip-flop design, and is used in a variety of applications, such as data storage, counters, control systems and frequency dividers.

The MC74AC74DR2G has two independent D-type flip-flops, with each flip-flop having an input (DIN1/DIN2), an output (Q1/Q2) and an active-low reset (R1/R2). The inputs are active-high, and the outputs are complementary (Q1/Q2, Q1/Q2 respectively). The devices are powered from the +5V supply, and feature an extended VCC operating range from +3V to +5.5V.

The MC74AC74DR2G has two applications, the "set-reset" flip-flop and the "data-latched" flip-flop. In the "set-reset" configuration, a logic "1" is applied to the DIN1 and R2 inputs, and a logic "0" is applied to the DIN2 and R1 inputs. When the logic "1" is applied to DIN1 and R2, the Q1 output will be set to logic "1". When the logic "0" is applied to DIN2 and R1, the Q2 output will be reset to logic "0". The device can be used in this configuration to store a single bit of data.

In the "data-latched" configuration, the MC74AC74DR2G can be used to store two different bits of data. In this configuration, a logic "1" is applied to the DIN1 and R2 inputs, while a logic "0" is applied to the DIN2 and R1 inputs. When the logic "1" is applied to DIN1 and R2, the Q1 output will be set to logic "1". When the logic "0" is applied to DIN2 and R1, the Q2 output will be reset to logic "0", and the Q1 output will remain latched to logic "1". The device can be used in this configuration to store two different bits of data.

The MC74AC74DR2G is a versatile and reliable device, suitable for a wide range of applications. It is ideal for use in data storage and counters, as well as in control and frequency division systems. It is also extremely low-power and easy to use, making it an ideal choice for many logic circuit applications.
