HEF4060BT from Nexperia, in a SOIC-16. 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	Q11	output	Buffered counter output for the 11th ripple-carry stage. CMOS push-pull output; VOH >= VDD-0.05 V at
2	Q12	output	Buffered counter output for the 12th ripple-carry stage. CMOS push-pull output.
3	Q13	output	Buffered counter output for the 13th ripple-carry stage. CMOS push-pull output.
4	Q5	output	Buffered counter output for the 5th ripple-carry stage. CMOS push-pull output.
5	Q4	output	Buffered counter output for the 4th ripple-carry stage. CMOS push-pull output.
6	Q6	output	Buffered counter output for the 6th ripple-carry stage. CMOS push-pull output.
7	Q3	output	Buffered counter output for the 3rd ripple-carry stage. CMOS push-pull output.
8	VSS	power_in	Ground supply voltage (0 V reference).
9	CEXT	passive	External capacitor connection for the on-chip RC/crystal oscillator. Leave floating when driving RS with an external clock.
10	REXT	passive	Oscillator pin; external resistor connection for the on-chip RC/crystal oscillator. Leave floating when driving RS with an external clock.
11	RS	input	Clock input / oscillator pin. Counter advances on HIGH-to-LOW transition of RS. May be driven by an external clock signal in lieu of using the internal oscillator.
12	MR	input	Master reset (asynchronous, active HIGH). A HIGH level clears all counter stages and forces all outputs LOW independent of other inputs.
13	Q8	output	Buffered counter output for the 8th ripple-carry stage. CMOS push-pull output.
14	Q7	output	Buffered counter output for the 7th ripple-carry stage. CMOS push-pull output.
15	Q9	output	Buffered counter output for the 9th ripple-carry stage. CMOS push-pull output.
16	VDD	power_in	Positive supply voltage. Operating range 3.0 V to 15.0 V (absolute max +18 V). Bypass close to the pin.
