XD74LS47 from XINLUDA, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | BCD input B; TTL-compatible, VIH ≥ 2 V, VIL ≤ 0.8 V. |
| 2 | C | input | BCD input C; TTL-compatible, VIH ≥ 2 V, VIL ≤ 0.8 V. |
| 3 | /LT | input | Lamp-test input (active low); when low, all seven segment outputs are forced on regardless of other inputs. |
| 4 | BI/RBO | bidirectional | Dual-function node: Blanking Input (active-low, overrides all outputs) and Ripple Blanking Output (driven low when a leading/trailing zero is blanked); IOH −50 µA, IOL 3.2 mA. |
| 5 | /RBI | input | Ripple Blanking Input (active low); blanks the display and asserts RBO when all BCD inputs and RBI are low, enabling leading/trailing zero suppression. |
| 6 | D | input | BCD input D (MSB); TTL-compatible, VIH ≥ 2 V, VIL ≤ 0.8 V. |
| 7 | A | input | BCD input A (LSB); TTL-compatible, VIH ≥ 2 V, VIL ≤ 0.8 V. |
| 8 | GND | power_in | Ground reference (0 V). |
| 9 | e | tri_state | Segment e output; active-low open-collector for direct common-anode LED drive; IO(on) up to 24 mA, VO(off) up to 15 V. |
| 10 | d | tri_state | Segment d output; active-low open-collector for direct common-anode LED drive; IO(on) up to 24 mA, VO(off) up to 15 V. |
| 11 | c | tri_state | Segment c output; active-low open-collector for direct common-anode LED drive; IO(on) up to 24 mA, VO(off) up to 15 V. |
| 12 | b | tri_state | Segment b output; active-low open-collector for direct common-anode LED drive; IO(on) up to 24 mA, VO(off) up to 15 V. |
| 13 | a | tri_state | Segment a output; active-low open-collector for direct common-anode LED drive; IO(on) up to 24 mA, VO(off) up to 15 V. |
| 14 | g | tri_state | Segment g output; active-low open-collector for direct common-anode LED drive; IO(on) up to 24 mA, VO(off) up to 15 V. |
| 15 | f | tri_state | Segment f output; active-low open-collector for direct common-anode LED drive; IO(on) up to 24 mA, VO(off) up to 15 V. |
| 16 | VCC | power_in | Positive supply voltage; 4.75 V min, 5 V nom, 5.25 V max; ICC 7 mA typ / 13 mA max. |
