CD74HC85PWR

Texas Instruments · Digital Comparators · TSSOP-16

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.

CAD (KiCad official)

  • Symbol: CD74HC85PWR
  • Footprint: Package_SO:TSSOP-16_4.4x5mm_P0.65mm
  • 3D model: TSSOP-16 (KiCad packages3D, STEP)
  • 3D model files: cd74hc85pwr-etched.step / cd74hc85pwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cd74hc85pwr.step / cd74hc85pwr.glb are the bare package body.
