**Texas Instruments** · Translators, Level Shifters · TSSOP-24

CLVCC4245AMPWREP from Texas Instruments, in a TSSOP-24. 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 | VCCA | power_in | A-port and control-circuitry supply, 4.5 V to 5.5 V (5 V nominal); DIR and OE input levels are referenced to VCCA. |
| 2 | DIR | input | Direction-control input: high transmits A data to B bus, low transmits B data to A bus, with VIH/VIL referenced to VCCA. |
| 3 | A1 | bidirectional | A-port channel 1 I/O, referenced to VCCA (4.5 V to 5.5 V), 3-state. |
| 4 | A2 | bidirectional | A-port channel 2 I/O, referenced to VCCA (4.5 V to 5.5 V), 3-state. |
| 5 | A3 | bidirectional | A-port channel 3 I/O, referenced to VCCA (4.5 V to 5.5 V), 3-state. |
| 6 | A4 | bidirectional | A-port channel 4 I/O, referenced to VCCA (4.5 V to 5.5 V), 3-state. |
| 7 | A5 | bidirectional | A-port channel 5 I/O, referenced to VCCA (4.5 V to 5.5 V), 3-state. |
| 8 | A6 | bidirectional | A-port channel 6 I/O, referenced to VCCA (4.5 V to 5.5 V), 3-state. |
| 9 | A7 | bidirectional | A-port channel 7 I/O, referenced to VCCA (4.5 V to 5.5 V), 3-state. |
| 10 | A8 | bidirectional | A-port channel 8 I/O, referenced to VCCA (4.5 V to 5.5 V), 3-state. |
| 11 | GND | power_in | Ground; connect ground before any supply voltage is applied. |
| 12 | GND | power_in | Ground; connect ground before any supply voltage is applied. |
| 13 | GND | power_in | Ground; connect ground before any supply voltage is applied. |
| 14 | B8 | bidirectional | B-port channel 8 I/O, referenced to VCCB (2.7 V to 5.5 V), 3-state. |
| 15 | B7 | bidirectional | B-port channel 7 I/O, referenced to VCCB (2.7 V to 5.5 V), 3-state. |
| 16 | B6 | bidirectional | B-port channel 6 I/O, referenced to VCCB (2.7 V to 5.5 V), 3-state. |
| 17 | B5 | bidirectional | B-port channel 5 I/O, referenced to VCCB (2.7 V to 5.5 V), 3-state. |
| 18 | B4 | bidirectional | B-port channel 4 I/O, referenced to VCCB (2.7 V to 5.5 V), 3-state. |
| 19 | B3 | bidirectional | B-port channel 3 I/O, referenced to VCCB (2.7 V to 5.5 V), 3-state. |
| 20 | B2 | bidirectional | B-port channel 2 I/O, referenced to VCCB (2.7 V to 5.5 V), 3-state. |
| 21 | B1 | bidirectional | B-port channel 1 I/O, referenced to VCCB (2.7 V to 5.5 V), 3-state. |
| 22 | OE | input | Output-enable input: high disables the device and isolates the buses, with VIH/VIL referenced to VCCA. |
| 23 | NC | unconnected | No internal connection. |
| 24 | VCCB | power_in | B-port supply, 2.7 V to 5.5 V (3.3 V nominal). |
