SN74HC247N from lingxingic, 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 | BCD data input B (weight 2), used with A, C and D to select the displayed digit. |
| 2 | C | input | BCD data input C (weight 4), used with A, B and D to select the displayed digit. |
| 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 | Active-low blanking input turns all segment outputs off when low, and also serves as ripple blanking output, which goes low when RBI and A-D are low with LT high. |
| 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 data input D (most significant bit), used with A, B and C to select the displayed digit. |
| 7 | A | input | BCD data input A (least significant bit), used with B, C and D to select the displayed digit. |
| 8 | GND | power_in | Ground (0 V) supply pin. |
| 9 | e | output | Active-low segment e data output for driving a common-anode LED, rated up to ±25 mA output current. |
| 10 | d | output | Active-low segment d data output for driving a common-anode LED, rated up to ±25 mA output current. |
| 11 | c | output | Active-low segment c data output for driving a common-anode LED, rated up to ±25 mA output current. |
| 12 | b | output | Active-low segment b data output for driving a common-anode LED, rated up to ±25 mA output current. |
| 13 | a | output | Active-low segment a data output for driving a common-anode LED, rated up to ±25 mA output current. |
| 14 | g | output | Active-low segment g data output for driving a common-anode LED, rated up to ±25 mA output current. |
| 15 | f | output | Active-low segment f data output for driving a common-anode LED, rated up to ±25 mA output current. |
| 16 | VCC | power_in | Supply voltage, 2.0 V to 6.0 V recommended for SN74HC247 (absolute maximum +7 V). |
