CD74HC85PWR from Texas Instruments, in a TSSOP-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 | B3 | input | Most significant bit of 4-bit word B, compared against A3. |
| 2 | (A<B) IN | input | Cascading input for A<B from a previous stage, used for serial or parallel expansion; must not be left floating. |
| 3 | (A=B) IN | input | Cascading input for A=B from a previous stage, used for serial or parallel expansion; must not be left floating. |
| 4 | (A>B) IN | input | Cascading input for A>B from a previous stage, used for serial or parallel expansion; must not be left floating. |
| 5 | (A>B) OUT | output | Buffered output that goes high when word A is greater than word B. |
| 6 | (A=B) OUT | output | Buffered output that goes high when word A equals word B. |
| 7 | (A<B) OUT | output | Buffered output that goes high when word A is less than word B. |
| 8 | GND | power_in | Ground reference. |
| 9 | B0 | input | Least significant bit of 4-bit word B, compared against A0. |
| 10 | A0 | input | Least significant bit of 4-bit word A, compared against B0. |
| 11 | B1 | input | Bit 1 of 4-bit word B, compared against A1. |
| 12 | A1 | input | Bit 1 of 4-bit word A, compared against B1. |
| 13 | A2 | input | Bit 2 of 4-bit word A, compared against B2. |
| 14 | B2 | input | Bit 2 of 4-bit word B, compared against A2. |
| 15 | A3 | input | Most significant bit of 4-bit word A, compared against B3. |
| 16 | VCC | power_in | Supply voltage, 2 V to 6 V for HC types (absolute max 7 V); a 0.1-µF bypass capacitor close to the pin is recommended. |
