Package
The SN74LV273ANSR is packaged in a 20-pin TSSOP (Thin Shrink Small Outline Package).
Pinout
The SN74LV273ANSR is an octal D-type flip-flop with a total of 20 pins. Its primary function is to store data, with each flip-flop capable of capturing and holding one bit of information. The device features eight parallel data inputs (D0 to D7), an active-low output enable (OE), a clock input (CLK), and a reset input (CLR).
When the clock signal (CLK) transitions from low to high, the flip-flops capture the data present on the inputs (D0 to D7) and transfer it to the corresponding outputs (Q0 to Q7). The outputs remain unchanged until the next clock pulse. The reset (CLR) input, when activated, sets all outputs to low regardless of the clock state.
This device is commonly used in applications requiring data storage and manipulation in digital circuits, particularly in low-voltage environments, as it operates within a supply voltage range of 2.7V to 3.6V.
