74VHCT126AFT from TOSHIBA, in a TSSOP-14. 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 | 1G | input | Active-high 3-state output enable for buffer 1; output 1Y is high impedance when 1G is low. |
| 2 | 1A | input | Data input of buffer 1, TTL-compatible with VIL 0.8 V max and VIH 2.0 V min, accepts 0 to 5.5 V. |
| 3 | 1Y | tri_state | 3-state output of buffer 1, high impedance when 1G is low, 0 to 5.5 V allowed in off-state. |
| 4 | 2G | input | Active-high 3-state output enable for buffer 2; output 2Y is high impedance when 2G is low. |
| 5 | 2A | input | Data input of buffer 2, TTL-compatible with VIL 0.8 V max and VIH 2.0 V min, accepts 0 to 5.5 V. |
| 6 | 2Y | tri_state | 3-state output of buffer 2, high impedance when 2G is low, 0 to 5.5 V allowed in off-state. |
| 7 | GND | power_in | Ground pin (0 V). |
| 8 | 3Y | tri_state | 3-state output of buffer 3, high impedance when 3G is low, 0 to 5.5 V allowed in off-state. |
| 9 | 3A | input | Data input of buffer 3, TTL-compatible with VIL 0.8 V max and VIH 2.0 V min, accepts 0 to 5.5 V. |
| 10 | 3G | input | Active-high 3-state output enable for buffer 3; output 3Y is high impedance when 3G is low. |
| 11 | 4Y | tri_state | 3-state output of buffer 4, high impedance when 4G is low, 0 to 5.5 V allowed in off-state. |
| 12 | 4A | input | Data input of buffer 4, TTL-compatible with VIL 0.8 V max and VIH 2.0 V min, accepts 0 to 5.5 V. |
| 13 | 4G | input | Active-high 3-state output enable for buffer 4; output 4Y is high impedance when 4G is low. |
| 14 | VCC | power_in | Supply voltage, recommended 4.5 to 5.5 V, absolute maximum -0.5 to 7.0 V. |
