CD4520BM96

Texas Instruments · Counters, Dividers · SOIC-16

CD4520BM96 from Texas Instruments, in a SOIC-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 for counter section A; counts advance on the selected clock edge (positive- or negative-going, set via internal exclusive-OR with ENABLE A) while RESET A is low.
2 ENABLE A input Enable input for counter section A; held high for single-unit operation so the counter advances on the positive-going CLOCK A transition, or used with CLOCK A for edge-select/cascading (e.g., driven by Q4 of a preceding stage for ripple cascading).
3 Q1A output Bit 1 (LSB) output of the 4-stage binary counter section A.
4 Q2A output Bit 2 output of the 4-stage binary counter section A.
5 Q3A output Bit 3 output of the 4-stage binary counter section A.
6 Q4A output Bit 4 (MSB) output of the 4-stage binary counter section A; can drive ENABLE B of a subsequent stage for ripple cascading.
7 RESET A input Asynchronous reset input for counter section A; a high level clears outputs Q1A-Q4A to 0 regardless of CLOCK A or ENABLE A state.
8 VSS power_in Negative supply / ground reference terminal for the device (0 V, referenced by VDD range -0.5 V to +20 V).
9 CLOCK B input Clock input for counter section B; counts advance on the selected clock edge while RESET B is low, identical function to CLOCK A.
10 ENABLE B input Enable input for counter section B; held high for single-unit operation so the counter advances on the positive-going CLOCK B transition, or used for edge-select/cascading.
11 Q1B output Bit 1 (LSB) output of the 4-stage binary counter section B.
12 Q2B output Bit 2 output of the 4-stage binary counter section B.
13 Q3B output Bit 3 output of the 4-stage binary counter section B.
14 Q4B output Bit 4 (MSB) output of the 4-stage binary counter section B.
15 RESET B input Asynchronous reset input for counter section B; a high level clears outputs Q1B-Q4B to 0 regardless of CLOCK B or ENABLE B state.
16 VDD power_in Positive supply voltage terminal, referenced to VSS; absolute maximum rating -0.5 V to +20 V, recommended operating range 3 V to 18 V.
