The Texas Instruments SN74LVC1G74DCKR is a single positive-edge-triggered D-type flip-flop with clear and preset in a 6-pin SC-70 (DCK) package. Operating from 1.65V to 5.5V VCC, it features overvoltage-tolerant inputs, high-speed operation (5.9ns max tpd at 3.3V), and Ioff support for partial power-down operation.<\/p>\n

Operating from 1.65V to 5.5V, it provides flexible voltage interfacing with overvoltage-tolerant inputs up to 5.5V. The Ioff feature enables partial power-down operation, making it suitable for battery-powered and hot-swap applications.","working_principle":"The SN74LVC1G74DCKR consists of a single D-type flip-flop with asynchronous clear (CLR) and preset (PRE) inputs. Data at the D input is transferred to the Q output on the rising edge of the clock (CLK). The CLR and PRE inputs are active-low and override the clock and data inputs. The LVC (Low-Voltage CMOS) logic family provides high-speed operation with low power consumption. The Ioff circuitry disables the outputs when VCC is 0V, preventing damaging current backflow during partial power-down.","pin_description":"
