**Texas Instruments** · Digital Tube Drivers · PDIP-16

CD4511BEE4 from Texas Instruments, in a PDIP-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, latched when LE/STROBE is high, with input voltage range -0.5 V to VDD+0.5 V. |
| 2 | C | input | BCD data input C, latched when LE/STROBE is high, with input voltage range -0.5 V to VDD+0.5 V. |
| 3 | LT | input | Active-low lamp test input that turns on all seven segment outputs when low, regardless of the other inputs. |
| 4 | BL | input | Active-low blanking input that turns all seven segment outputs off when low. |
| 5 | LE/STROBE | input | Latch enable/strobe input that stores the BCD code when high, while the outputs follow the inputs when low. |
| 6 | D | input | BCD data input D, latched when LE/STROBE is high, where codes above 1001 blank the display. |
| 7 | A | input | BCD data input A, latched when LE/STROBE is high, with input voltage range -0.5 V to VDD+0.5 V. |
| 8 | VSS | power_in | Ground (negative supply) terminal, the reference for the -0.5 V to +20 V VDD supply-voltage rating. |
| 9 | e | output | Segment e output of the 7-segment decoder, able to source up to 25 mA, with 100 mW maximum dissipation per output transistor. |
| 10 | d | output | Segment d output of the 7-segment decoder, able to source up to 25 mA, with 100 mW maximum dissipation per output transistor. |
| 11 | c | output | Segment c output of the 7-segment decoder, able to source up to 25 mA, with 100 mW maximum dissipation per output transistor. |
| 12 | b | output | Segment b output of the 7-segment decoder, able to source up to 25 mA, with 100 mW maximum dissipation per output transistor. |
| 13 | a | output | Segment a output of the 7-segment decoder, able to source up to 25 mA, with 100 mW maximum dissipation per output transistor. |
| 14 | g | output | Segment g output of the 7-segment decoder, able to source up to 25 mA, with 100 mW maximum dissipation per output transistor. |
| 15 | f | output | Segment f output of the 7-segment decoder, able to source up to 25 mA, with 100 mW maximum dissipation per output transistor. |
| 16 | VDD | power_in | Positive supply terminal, with a recommended operating range of 3 V to 18 V and an absolute maximum of -0.5 V to +20 V. |
