Quick Sourcing Note

SN74LVC1G374 from Texas Instruments is a Signal_Chain single positive-edge-triggered D-type flip-flop with a 3-state output. It operates from a 1.65-5.5 V supply, supports 1.5 V minimum data retention, and accepts 0-5.5 V inputs. Package options include 6-pin SOT-23 (DBV), 6-pin SC70 (DCK), and YEP/YZP NanoStar/NanoFree packages. It is suited to clocked data capture, output isolation, and compact logic interfacing where the Q output follows D on a rising CLK edge while OE is low. Key limits include -40 to 125 °C operation, up to 175 MHz minimum clock frequency at 5 V, and ±50 mA absolute maximum continuous output current.
