Sets the reference rail for the A-side I/Os and the DIR/OE control-input thresholds. 1.2V ≤ V_CCA ≤ 3.6V. |+| 2 | 1DIR | input | Direction-control input for channel 1 ports (1A1/1A2 ↔ 1B1/1B2). Referenced to V_CCA. HIGH transmits A→B; LOW transmits B→A. |+| 3 | 2DIR | input | Direction-control input for channel 2 ports (2A1/2A2 ↔ 2B1/2B2). Referenced to V_CCA. |+| 4 | 1A1 | bidirectional | Channel-1 A-port I/O, bit 1. Voltage levels referenced to V_CCA. Direction set by 1DIR; output-disabled when 1OE is HIGH (Hi-Z). |+| 5 | 1A2 | bidirectional | Channel-1 A-port I/O, bit 2. Voltage levels referenced to V_CCA. |+| 6 | 2A1 | bidirectional | Channel-2 A-port I/O, bit 1. Voltage levels referenced to V_CCA. Direction set by 2DIR; output-disabled when 2OE is HIGH (Hi-Z). |+| 7 | 2A2 | bidirectional | Channel-2 A-port I/O, bit 2. Voltage levels referenced to V_CCA. |+| 8 | GND | power_in | Device ground (0 V) reference for both port supplies. |+| 9 | GND | power_in | Device ground (0 V) reference for both port supplies. |+| 10 | 2B2 | bidirectional | Channel-2 B-port I/O, bit 2. Voltage levels referenced to V_CCB. |+| 11 | 2B1 | bidirectional | Channel-2 B-port I/O, bit 1. Voltage levels referenced to V_CCB. |+| 12 | 1B2 | bidirectional | Channel-1 B-port I/O, bit 2. Voltage levels referenced to V_CCB. |+| 13 | 1B1 | bidirectional | Channel-1 B-port I/O, bit 1. Voltage levels referenced to V_CCB. |+| 14 | 2OE | input | Active-low 3-state output enable for channel 2. Pull HIGH to place both 2A and 2B outputs into Hi-Z. Referenced to V_CCA. |+| 15 | 1OE | input | Active-low 3-state output enable for channel 1. Pull HIGH to place both 1A and 1B outputs into Hi-Z. Referenced to V_CCA. |+| 16 | VCCB | power_in | B-port power supply. Sets the reference rail for the B-side I/Os. 1.2V ≤ V_CCB ≤ 3.6V. Fully independent of V_CCA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `SN74AVC4T245DRDR`+- `SN74AVC4T245DRD`+- `SN74AVC4T245DRDGV`+- `SN74AVC4T245DRDGVR`+- `SN74AVC4T245DRPW`+- `SN74AVC4T245DRPWR`+- `SN74AVC4T245DRRGY`+- `SN74AVC4T245DRRGYR`+- `SN74AVC4T245DRRSV`+- `SN74AVC4T245DRRSVR`+- `SN74AVC4T245DRBQB`+- `SN74AVC4T245DRWBQB`+- `SN74AVC4T245DRDYY`+- `SN74AVC4T245DRDYYR`++## CAD (KiCad official)++- Symbol: `SN74AVC4T245DR`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/sn74avc4t245.pdf) (46 pp, sha256 `218e7e3a60f567bb`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
