**Texas Instruments** · Signal Switches, Multiplexers, Decoders · SOIC-16

CD4532BM96 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 | D4 | input | Priority encoder data input 4; inputs D7-D0 each have an assigned priority. |
| 2 | D5 | input | Priority encoder data input 5; inputs D7-D0 each have an assigned priority. |
| 3 | D6 | input | Priority encoder data input 6; inputs D7-D0 each have an assigned priority. |
| 4 | D7 | input | Highest-priority data input of the 8-bit priority encoder. |
| 5 | EI | input | Chip-enable input; the encoder is inhibited when EI is low and active when EI is high. |
| 6 | Q2 | output | Binary code output bit 2 (MSB) giving the highest-priority active input when EI is high. |
| 7 | Q1 | output | Binary code output bit 1 giving the highest-priority active input when EI is high. |
| 8 | VSS | power_in | Ground supply terminal; all voltages are referenced to VSS. |
| 9 | Q0 | output | Binary code output bit 0 (LSB) giving the highest-priority active input when EI is high. |
| 10 | D0 | input | Lowest-priority data input of the 8-bit priority encoder. |
| 11 | D1 | input | Priority encoder data input 1; inputs D7-D0 each have an assigned priority. |
| 12 | D2 | input | Priority encoder data input 2; inputs D7-D0 each have an assigned priority. |
| 13 | D3 | input | Priority encoder data input 3; inputs D7-D0 each have an assigned priority. |
| 14 | GS | output | Group select output, high to indicate that priority inputs are present. |
| 15 | EO | output | Enable-out, high when no priority inputs are present and low when any input is high, disabling cascaded lower-order stages. |
| 16 | VDD | power_in | Positive supply; recommended range 3 V to 18 V, absolute maximum -0.5 V to +20 V referenced to VSS. |
