Description
The SN74LVC74ADR is a dual positive-edge-triggered D-type flip-flop with set and reset functions, designed by Texas Instruments. It is part of the LVC family, which is known for low-voltage, high-performance digital logic circuits. The device operates within a voltage range of 1.65V to 3.6V, making it suitable for various low-power applications.
Each flip-flop in the SN74LVC74ADR has data (D), clock (CLK), set (SET), and reset (RESET) inputs, along with complementary outputs (Q and Q̅). The flip-flop changes state on the rising edge of the clock signal, and the state can be asynchronously set or reset by the respective inputs.
The SN74LVC74ADR is housed in a small-outline (SOIC) package, suitable for surface-mount technology. The device is characterized by its high-speed operation, low power consumption, and robust performance across a wide temperature range, making it ideal for use in portable and battery-powered equipment, communication devices, and various digital logic applications.
