CD4028BM96 from Texas Instruments, 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	Q4	output	Decoded decimal output 4. Active-high CMOS output, sourcing/sinking rail-to-rail at VDD/VSS.
2	Q2	output	Decoded decimal output 2. Active-high CMOS output.
3	Q0	output	Decoded decimal output 0. Active-high CMOS output; also asserted for any invalid BCD input when used as BCD-to-decimal decoder.
4	Q7	output	Decoded decimal output 7. Active-high CMOS output.
5	Q9	output	Decoded decimal output 9. Active-high CMOS output.
6	Q5	output	Decoded decimal output 5. Active-high CMOS output.
7	Q6	output	Decoded decimal output 6. Active-high CMOS output.
8	VSS	power_in	Negative supply / ground reference (0 V).
9	D	input	BCD input D (MSB, weight 8). CMOS logic input; tie unused BCD inputs to VSS for binary-to-octal operation.
10	A	input	BCD input A (LSB, weight 1). CMOS logic input.
11	B	input	BCD input B (weight 2). CMOS logic input.
12	C	input	BCD input C (weight 4). CMOS logic input.
13	Q3	output	Decoded decimal output 3. Active-high CMOS output.
14	Q8	output	Decoded decimal output 8. Active-high CMOS output.
15	Q1	output	Decoded decimal output 1. Active-high CMOS output.
16	VDD	power_in	Positive supply rail. Operating range 3 V to 18 V (absolute max 20 V).
