SN74LVC2G74DCUR from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	CLK	input	Clock input. Data at D is transferred to Q on the positive-going edge of CLK when PRE and CLR are inactive (high). Accepts input voltages up to 5.5 V regardless of VCC.
2	D	input	Data input. Sampled on the rising edge of CLK and transferred to Q when PRE and CLR are inactive high. Input tolerant to 5.5 V.
3	~{Q}	output	Complementary (inverted) flip-flop output. Drives ±24 mA at VCC = 3.3 V. Goes high when the internal Q latch is reset by CLR = L.
4	GND	power_in	Ground reference (0 V) for the device.
5	Q	output	True flip-flop output. Reflects the state of the D input following the rising edge of CLK. Drives ±24 mA at VCC = 3.3 V.
6	~{CLR}	input	Active-low asynchronous clear input. A low level forces Q low regardless of CLK or D. Must be held high for normal clocked operation.
7	~{PRE}	input	Active-low asynchronous preset input. A low level forces Q high regardless of CLK or D. Must be held high for normal clocked operation.
8	VCC	power_in	Positive supply voltage. Operating range 1.65 V to 5.5 V; data retention down to 1.5 V. Bypass locally with a 0.1 µF ceramic capacitor to GND.
