CD4518BM

HGSEMI · Counters, Dividers · SOP-16

CD4518BM from HGSEMI, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CLOCK A input Clock input of counter A, which increments on the positive-going transition when ENABLE A is held high.
2 ENABLE A input Enable input of counter A, interchangeable with CLOCK for incrementing on the negative-going transition, and held high for single-unit operation.
3 Q1A output Counter A stage 1 output.
4 Q2A output Counter A stage 2 output.
5 Q3A output Counter A stage 3 output.
6 Q4A output Counter A stage 4 output, which can be connected to the enable input of the next counter for ripple cascading.
7 RESET A input Reset input of counter A, where a high level clears Q1 through Q4 to 0.
8 VSS power_in Ground (VSS) reference for the supply.
9 CLOCK B input Clock input of counter B, which increments on the positive-going transition when ENABLE B is held high.
10 ENABLE B input Enable input of counter B, interchangeable with CLOCK for incrementing on the negative-going transition, and held high for single-unit operation.
11 Q1B output Counter B stage 1 output.
12 Q2B output Counter B stage 2 output.
13 Q3B output Counter B stage 3 output.
14 Q4B output Counter B stage 4 output, which can be connected to the enable input of the next counter for ripple cascading.
15 RESET B input Reset input of counter B, where a high level clears Q1 through Q4 to 0.
16 VDD power_in Positive supply, recommended 3V to 15V and absolute maximum 18V relative to VSS.
