**Texas Instruments** · Translators, Level Shifters · PDIP-16

CD4504BE 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 | VCC | power_in | Input-side supply for the logic level; VCC can exceed VDD, and input voltage range is -0.5 V to VCC + 0.5 V. |
| 2 | A OUT | output | Level-shifted output of circuit A, swinging between VSS and VDD. |
| 3 | A IN | input | Input of circuit A; input range -0.5 V to VCC + 0.5 V, max input current ±10 mA. |
| 4 | B OUT | output | Level-shifted output of circuit B, swinging between VSS and VDD. |
| 5 | B IN | input | Input of circuit B; input range -0.5 V to VCC + 0.5 V, max input current ±10 mA. |
| 6 | C OUT | output | Level-shifted output of circuit C, swinging between VSS and VDD. |
| 7 | C IN | input | Input of circuit C; input range -0.5 V to VCC + 0.5 V, max input current ±10 mA. |
| 8 | VSS | power_in | Ground/negative supply reference; VDD voltages are referenced to this terminal. |
| 9 | D IN | input | Input of circuit D; input range -0.5 V to VCC + 0.5 V, max input current ±10 mA. |
| 10 | D OUT | output | Level-shifted output of circuit D, swinging between VSS and VDD. |
| 11 | E IN | input | Input of circuit E; input range -0.5 V to VCC + 0.5 V, max input current ±10 mA. |
| 12 | E OUT | output | Level-shifted output of circuit E, swinging between VSS and VDD. |
| 13 | SELECT | input | Mode select: HIGH (VCC) gives TTL-to-CMOS shifting, LOW gives CMOS-to-CMOS shifting; only CMOS-CMOS thresholds apply. |
| 14 | F IN | input | Input of circuit F; input range -0.5 V to VCC + 0.5 V, max input current ±10 mA. |
| 15 | F OUT | output | Level-shifted output of circuit F, swinging between VSS and VDD. |
| 16 | VDD | power_in | Output-side positive supply; DC supply range is -0.5 V to +20 V referenced to VSS. |
