SN74HC47N 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 | B | input | Data input B of the BCD code (weight 2). |
| 2 | C | input | Data input C of the BCD code (weight 4). |
| 3 | LT | input | Active-low lamp test input; when low with BI/RBO open or high, all segment outputs are on. |
| 4 | BI/RBO | bidirectional | Blanking input/ripple-blanking output; must be open or high for output functions 0 through 15, a low level applied turns all segment outputs off, and RBO goes low when ripple blanking occurs. |
| 5 | RBI | input | Active-low ripple blanking input; must be open or high if blanking of a decimal zero is not desired. |
| 6 | D | input | Data input D of the BCD code (weight 8). |
| 7 | A | input | Data input A of the BCD code (weight 1). |
| 8 | GND | power_in | Ground (0V). |
| 9 | e | output | Active-low data output for segment e. |
| 10 | d | output | Active-low data output for segment d. |
| 11 | c | output | Active-low data output for segment c. |
| 12 | b | output | Active-low data output for segment b. |
| 13 | a | output | Active-low data output for segment a. |
| 14 | g | output | Active-low data output for segment g. |
| 15 | f | output | Active-low data output for segment f. |
| 16 | VCC | power_in | Supply voltage, 2V to 6V. |
