CD4511BM from HGSEMI, in a SOP-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 B input BCD input bit B (weight 2). CMOS input, VIH ~= 3.5 V @ VDD=5 V; VIL ~= 1.5 V @ VDD=5 V. Latched into internal storage on LE low->high transition.
2 C input BCD input bit C (weight 4). CMOS input referenced to VSS/VDD; input current typ +/-0.1 uA @ VDD=15 V.
3 LT input Lamp Test, active low. When LT=0, all seven segment outputs (a..g) are forced high regardless of other inputs (displays '8' / all segments on) for lamp verification.
4 BI input Blanking Input, active low. When BI=0 (and LT=1), all segment outputs are forced low, blanking the display. Can be driven with a PWM signal for intensity modulation.
5 LE input Latch Enable. LE=0 the latch is transparent and follows the D/C/B/A inputs; on LE 0->1 the current BCD code is stored and the outputs are held. Minimum latch-enable pulse width 260 ns typ at VDD=5 V.
6 D input BCD input bit D (MSB, weight 8). Standard CMOS input, VIN range 0 V to VDD.
7 A input BCD input bit A (LSB, weight 1). Standard CMOS input, VIN range 0 V to VDD.
8 VSS power_in Negative supply / ground reference (0 V). Recommended operating VDD-VSS range 5 V to 15 V; absolute max 18 V.
9 e output Seven-segment decoded output 'e' (NPN bipolar source driver). Active high; sources up to 25 mA into a common-cathode LED segment. VOH typ 3.75 V @ VDD=5 V, IOH=20 mA.
10 d output Seven-segment decoded output 'd'. Active-high source driver, up to 25 mA per output.
11 c output Seven-segment decoded output 'c'. Active-high source driver, up to 25 mA per output.
12 b output Seven-segment decoded output 'b'. Active-high source driver, up to 25 mA per output.
13 a output Seven-segment decoded output 'a'. Active-high source driver, up to 25 mA per output.
14 g output Seven-segment decoded output 'g' (center segment). Active-high source driver, up to 25 mA per output.
15 f output Seven-segment decoded output 'f'. Active-high source driver, up to 25 mA per output.
16 VDD power_in Positive supply. Recommended 5 V to 15 V; absolute maximum 18 V. Quiescent supply current 5 uA typ (VDD=5 V) / 20 uA typ (VDD=15 V) at 25 C.
