Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | BCD address input used to define the decimal digit display along with A, C, D inputs. |
| 2 | C | input | BCD address input used to define the decimal digit display along with A, B, D inputs. |
| 3 | LT | input | Lamp test input (active LOW); drives all segment outputs HIGH when LOW, overriding all other inputs. |
| 4 | BI | input | Ripple blanking input (active LOW); drives all segment outputs LOW when LOW and LT is HIGH. |
| 5 | LE | input | Latch enable input (active LOW); latches BCD input data when transitioning from LOW to HIGH; segment outputs remain stable when LE is HIGH. |
| 6 | D | input | BCD address input used to define the decimal digit display along with A, B, C inputs. |
| 7 | A | input | BCD address input used to define the decimal digit display along with B, C, D inputs. |
| 8 | GND | power_in | Ground (0 V) reference for all signal levels. |
| 9 | e | output | 7-segment output capable of 10 mA drive for common cathode LED display segments. |
| 10 | d | output | 7-segment output capable of 10 mA drive for common cathode LED display segments. |
| 11 | c | output | 7-segment output capable of 10 mA drive for common cathode LED display segments. |
| 12 | b | output | 7-segment output capable of 10 mA drive for common cathode LED display segments. |
| 13 | a | output | 7-segment output capable of 10 mA drive for common cathode LED display segments. |
| 14 | g | output | 7-segment output capable of 10 mA drive for common cathode LED display segments. |
| 15 | f | output | 7-segment output capable of 10 mA drive for common cathode LED display segments. |
| 16 | VCC | power_out | Supply voltage; 2.0 V to 6.0 V for 74HC4511 or 4.5 V to 5.5 V for 74HCT4511. |
