Additional Details

The TC74VCX74FT(EL) consists of two independent D-type flip-flops. Each flip-flop has a data input (D), a clock input (CLK), a set input (SET), a reset input (RST), and complementary outputs (Q and Q\'). Data at the D input is transferred to the Q output on the positive-going edge of the clock pulse. The SET and RST inputs are asynchronous and override the clock and data inputs. When SET is low, the Q output is forced high. When RST is low, the Q output is forced low. The power-down protection feature prevents current leakage when the supply voltage is removed. The operating temperature range is -40°C to +85°C.

This flip-flop is commonly used in a variety of digital electronic systems where data storage and manipulation are required. The low-voltage operation makes it suitable for portable and battery-powered devices. The high-speed performance allows it to be used in high-frequency applications. The small package size makes it ideal for applications where board space is limited.
