# CD4043BE

**XBLW** · Latches · DIP-16

CD4043BE from XBLW, in a DIP-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 | 4Q | tri_state | 3-state buffered latch output for latch 4, high impedance when OE is LOW. |
| 2 | 1Q | tri_state | 3-state buffered latch output for latch 1, high impedance when OE is LOW. |
| 3 | 1R | input | Active HIGH reset input for latch 1. |
| 4 | 1S | input | Active HIGH set input for latch 1. |
| 5 | OE | input | Common output enable input; outputs are high impedance when LOW and follow the latches when HIGH. |
| 6 | 2S | input | Active HIGH set input for latch 2. |
| 7 | 2R | input | Active HIGH reset input for latch 2. |
| 8 | VSS | power_in | Ground supply voltage (VSS, usually ground). |
| 9 | 2Q | tri_state | 3-state buffered latch output for latch 2, high impedance when OE is LOW. |
| 10 | 3Q | tri_state | 3-state buffered latch output for latch 3, high impedance when OE is LOW. |
| 11 | 3R | input | Active HIGH reset input for latch 3. |
| 12 | 3S | input | Active HIGH set input for latch 3. |
| 13 | NC | unconnected | Not connected. |
| 14 | 4S | input | Active HIGH set input for latch 4. |
| 15 | 4R | input | Active HIGH reset input for latch 4. |
| 16 | VDD | power_in | Supply voltage, recommended range 3 V to 15 V referenced to VSS. |
