SN74HC247DR from lingxingic, 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 data input B; it is one of the four binary inputs (A, B, C, D) that select the decoded digit shown on the seven-segment outputs. |
| 2 | C | input | BCD data input C; it is one of the four binary inputs (A, B, C, D) that select the decoded digit shown on the seven-segment outputs. |
| 3 | LT | input | Lamp test input; when it is held low while BI/RBO is open or high, all segment outputs are turned on regardless of the data inputs. |
| 4 | BI/RBO | bidirectional | Blanking input / ripple blanking output; a low level applied to BI turns off all segment outputs regardless of the other inputs, and RBO goes low when RBI and A-D are low with LT high. |
| 5 | RBI | input | Ripple blanking input; it must be open or high if blanking of a decimal zero is not desired. |
| 6 | D | input | BCD data input D (most significant bit); it is one of the four binary inputs (A, B, C, D) that select the decoded digit shown on the seven-segment outputs. |
| 7 | A | input | BCD data input A (least significant bit); it is one of the four binary inputs (A, B, C, D) that select the decoded digit shown on the seven-segment outputs. |
| 8 | GND | power_in | Ground (0 V) reference for all voltages; absolute maximum ratings and electrical limits are referenced to GND. |
| 9 | e | output | Active-low segment e output for driving common-anode LEDs; absolute maximum output current is ±25 mA. |
| 10 | d | output | Active-low segment d output for driving common-anode LEDs; absolute maximum output current is ±25 mA. |
| 11 | c | output | Active-low segment c output for driving common-anode LEDs; absolute maximum output current is ±25 mA. |
| 12 | b | output | Active-low segment b output for driving common-anode LEDs; absolute maximum output current is ±25 mA. |
| 13 | a | output | Active-low segment a output for driving common-anode LEDs; absolute maximum output current is ±25 mA. |
| 14 | g | output | Active-low segment g output for driving common-anode LEDs; absolute maximum output current is ±25 mA. |
| 15 | f | output | Active-low segment f output for driving common-anode LEDs; absolute maximum output current is ±25 mA. |
| 16 | VCC | power_in | Supply voltage; recommended 2.0 V to 6.0 V for SN74HC247 and 4.5 V to 5.5 V for HCT247, absolute maximum -0.5 V to +7 V. |
