Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | 1OE | input | Output enable for group 1 (1Y0..1Y3), active low. High level tri-states the group-1 outputs. |+| 2 | 1A0 | input | Data input, channel 1 bit 0. Buffered to 1Y0 when 1OE is low. |+| 3 | 2Y0 | tri_state | Bus output, channel 2 bit 0. Follows 2A0 when 2OE is low; high-Z when 2OE is high. |+| 4 | 1A1 | input | Data input, channel 1 bit 1. Buffered to 1Y1 when 1OE is low. |+| 5 | 2Y1 | tri_state | Bus output, channel 2 bit 1. Follows 2A1 when 2OE is low; high-Z when 2OE is high. |+| 6 | 1A2 | input | Data input, channel 1 bit 2. Buffered to 1Y2 when 1OE is low. |+| 7 | 2Y2 | tri_state | Bus output, channel 2 bit 2. Follows 2A2 when 2OE is low; high-Z when 2OE is high. |+| 8 | 1A3 | input | Data input, channel 1 bit 3. Buffered to 1Y3 when 1OE is low. |+| 9 | 2Y3 | tri_state | Bus output, channel 2 bit 3. Follows 2A3 when 2OE is low; high-Z when 2OE is high. |+| 10 | GND | power_in | Ground reference, 0 V. |+| 11 | 2A3 | input | Data input, channel 2 bit 3. Buffered to 2Y3 when 2OE is low. |+| 12 | 1Y3 | tri_state | Bus output, channel 1 bit 3. Follows 1A3 when 1OE is low; high-Z when 1OE is high. |+| 13 | 2A2 | input | Data input, channel 2 bit 2. Buffered to 2Y2 when 2OE is low. |+| 14 | 1Y2 | tri_state | Bus output, channel 1 bit 2. Follows 1A2 when 1OE is low; high-Z when 1OE is high. |+| 15 | 2A1 | input | Data input, channel 2 bit 1. Buffered to 2Y1 when 2OE is low. |+| 16 | 1Y1 | tri_state | Bus output, channel 1 bit 1. Follows 1A1 when 1OE is low; high-Z when 1OE is high. |+| 17 | 2A0 | input | Data input, channel 2 bit 0. Buffered to 2Y0 when 2OE is low. |+| 18 | 1Y0 | tri_state | Bus output, channel 1 bit 0. Follows 1A0 when 1OE is low; high-Z when 1OE is high. |+| 19 | 2OE | input | Output enable for group 2 (2Y0..2Y3), active low. High level tri-states the group-2 outputs. |+| 20 | VCC | power_in | Supply voltage. Recommended 4.5-5.5 V for HCT variant (2.0-6.0 V for HC); absolute max 7.0 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Wuxi I core Elec AiP74HCT244TA20 TR |+| Package | TSSOP-20 |+| Category | Logic |+| Pins | 20 |++## Ordering variants++- `AiP74HCT244TA20.TRTA20.TR`+- `AiP74HCT244TA20.TRTA20.TB`+- `AiP74HCT244TA20.TRSA20.TR`+- `AiP74HCT244TA20.TRSA20.TB`+- `AiP74HCT244TA20.TRDA20.TB`++## CAD (KiCad official)++- Symbol: `AiP74HCT244TA20.TR`+- Footprint: `Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm`+- 3D model: TSSOP-20 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Wuxi I core Elec AiP74HCT244TA20 TR datasheet](docs/aip74hct244ta20-tr-datasheet.pdf) (18 pp, sha256 `36eef0eb359fbb5f`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
