# CD4035BM96

**Texas Instruments** · Shift Registers · SOIC-16

CD4035BM96 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 | Q1/Q̄1 | output | Stage 1 buffered output, true or complement depending on TRUE/COMPLEMENT control. |
| 2 | T/C | input | TRUE/COMPLEMENT control: high gives true register contents at outputs, low gives complements; acts asynchronously with respect to clock. |
| 3 | K̄ | input | Inverted K serial input to first stage JK logic; with J and K tied together the first stage acts as a D flip-flop. |
| 4 | J | input | J serial input to first stage JK logic. |
| 5 | RESET | input | Asynchronous common reset for the register. |
| 6 | CLK | input | Clock input; data is transferred on positive clock transitions in parallel or serial mode. |
| 7 | P/S | input | PARALLEL/SERIAL control: high permits synchronous parallel entry, low selects serial mode. |
| 8 | VSS | power_in | Ground (VSS); supply voltage is referenced to this terminal. |
| 9 | PI-1 | input | Parallel input to stage 1. |
| 10 | PI-2 | input | Parallel input to stage 2. |
| 11 | PI-3 | input | Parallel input to stage 3. |
| 12 | PI-4 | input | Parallel input to stage 4. |
| 13 | Q4/Q̄4 | output | Stage 4 buffered output, true or complement depending on TRUE/COMPLEMENT control. |
| 14 | Q3/Q̄3 | output | Stage 3 buffered output, true or complement depending on TRUE/COMPLEMENT control. |
| 15 | Q2/Q̄2 | output | Stage 2 buffered output, true or complement depending on TRUE/COMPLEMENT control. |
| 16 | VDD | power_in | Positive supply; recommended range 3 V to 18 V, absolute maximum -0.5 V to +20 V referenced to VSS. |
