CD4511BPWR from Texas Instruments, in a TSSOP-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; one of four BCD address inputs (A=LSB, D=MSB) decoded to drive 7-segment outputs for codes 0-9. |
| 2 | C | input | BCD data input C; one of four BCD address inputs (A=LSB, D=MSB) decoded to drive 7-segment outputs for codes 0-9. |
| 3 | ~LT | input | Lamp Test input, active-low; when asserted LOW (with ~BI HIGH), all seven segment outputs are forced HIGH to test display segments regardless of BCD inputs. |
| 4 | ~BI | input | Blanking Input, active-low; when asserted LOW, forces all seven segment outputs LOW, blanking the display regardless of all other inputs. |
| 5 | LE | input | Latch Enable (Strobe); when HIGH, the output latches retain the last BCD code applied; when LOW, outputs follow BCD inputs transparently. |
| 6 | D | input | BCD data input D (MSB); one of four BCD address inputs decoded to drive 7-segment outputs for codes 0-9. |
| 7 | A | input | BCD data input A (LSB); one of four BCD address inputs decoded to drive 7-segment outputs for codes 0-9. |
| 8 | VSS | power_in | Ground reference (0 V); negative supply terminal, all voltages referenced to this node. |
| 9 | e | output | 7-segment output e, active-HIGH push-pull; sourcing output capable of up to 25 mA for direct drive of common-cathode LED displays. |
| 10 | d | output | 7-segment output d, active-HIGH push-pull; sourcing output capable of up to 25 mA for direct drive of common-cathode LED displays. |
| 11 | c | output | 7-segment output c, active-HIGH push-pull; sourcing output capable of up to 25 mA for direct drive of common-cathode LED displays. |
| 12 | b | output | 7-segment output b, active-HIGH push-pull; sourcing output capable of up to 25 mA for direct drive of common-cathode LED displays. |
| 13 | a | output | 7-segment output a, active-HIGH push-pull; sourcing output capable of up to 25 mA for direct drive of common-cathode LED displays. |
| 14 | g | output | 7-segment output g, active-HIGH push-pull; sourcing output capable of up to 25 mA for direct drive of common-cathode LED displays. |
| 15 | f | output | 7-segment output f, active-HIGH push-pull; sourcing output capable of up to 25 mA for direct drive of common-cathode LED displays. |
| 16 | VDD | power_in | Positive supply voltage; operating range 3 V to 18 V (absolute maximum -0.5 V to +18 V referenced to VSS); parametric ratings at 5 V, 10 V, and 15 V. |
