Operating range 1.1V ≤ VCCA ≤ 5.5V. Sets the logic reference level for the A-side inputs (A1-A4). |+| 2 | A1 | input | Input A1, referenced to VCCA. Schmitt-trigger input with an internal pull-down resistor to prevent floating. |+| 3 | A2 | input | Input A2, referenced to VCCA. Schmitt-trigger input with an internal pull-down resistor. |+| 4 | A3 | input | Input A3, referenced to VCCA. Schmitt-trigger input with an internal pull-down resistor. |+| 5 | A4 | input | Input A4, referenced to VCCA. Schmitt-trigger input with an internal pull-down resistor. |+| 6 | NC | unconnected | No internal connection. May be left floating. |+| 7 | GND | power_in | Device ground reference. |+| 8 | OE | input | Output Enable (active-high on TXU0104). Pull to GND to place all B outputs in high-impedance mode; pull to VCCA or VCCB to enable outputs. Referenced to VCC(MIN). |+| 9 | NC | unconnected | No internal connection. May be left floating. |+| 10 | B4Y | tri_state | Output B4, referenced to VCCB. Push-pull 3-state output; drive up to 12 mA at 5V. High-Z when OE is inactive. |+| 11 | B3Y | tri_state | Output B3, referenced to VCCB. Push-pull 3-state output; high-Z when OE is inactive. |+| 12 | B2Y | tri_state | Output B2, referenced to VCCB. Push-pull 3-state output; high-Z when OE is inactive. |+| 13 | B1Y | tri_state | Output B1, referenced to VCCB. Push-pull 3-state output; high-Z when OE is inactive. |+| 14 | VCCB | power_in | B-port supply voltage. Operating range 1.1V ≤ VCCB ≤ 5.5V.
