SN74LS247DR from Texas Instruments, in a SOP-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 | BCD input B, one of four inputs (A, B, C, D) that select the displayed digit. |
| 2 | C | input | BCD input C, one of four inputs (A, B, C, D) that select the displayed digit. |
| 3 | LT | input | Active-low lamp test input; when BI/RBO is open or high, a low on LT turns all segment outputs on. |
| 4 | BI/RBO | bidirectional | Wire-AND blanking input (BI) and ripple-blanking output (RBO); a low on BI forces all segment outputs off, and RBO goes low when ripple blanking of a zero 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 | BCD input D, one of four inputs (A, B, C, D) that select the displayed digit. |
| 7 | A | input | BCD input A, one of four inputs (A, B, C, D) that select the displayed digit. |
| 8 | GND | power_in | Ground. |
| 9 | e | output | Segment e active-low open-collector output, sinks 24 mA with 15 V maximum for the SN74LS247. |
| 10 | d | output | Segment d active-low open-collector output, sinks 24 mA with 15 V maximum for the SN74LS247. |
| 11 | c | output | Segment c active-low open-collector output, sinks 24 mA with 15 V maximum for the SN74LS247. |
| 12 | b | output | Segment b active-low open-collector output, sinks 24 mA with 15 V maximum for the SN74LS247. |
| 13 | a | output | Segment a active-low open-collector output, sinks 24 mA with 15 V maximum for the SN74LS247. |
| 14 | g | output | Segment g active-low open-collector output, sinks 24 mA with 15 V maximum for the SN74LS247. |
| 15 | f | output | Segment f active-low open-collector output, sinks 24 mA with 15 V maximum for the SN74LS247. |
| 16 | VCC | power_in | Positive supply voltage. |
