TXU0101QDCKRQ1 from TEXAS INSTRUMENTS, in a SC-70-6. 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 supply voltage, which must be within 1.1 V to 5.5 V (1.1 V ≤ VCCA ≤ 5.5 V). |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | A | input | Input A, referenced to the VCCA logic level. |
| 4 | BY | output | Output B, referenced to the VCCB logic level; all outputs go high-impedance when OE is low. |
| 5 | OE | input | Output enable: pull to GND to place all outputs in high-impedance mode, or pull to VCCA or VCCB to enable all outputs. |
| 6 | VCCB | power_in | B-port supply voltage, which must be within 1.1 V to 5.5 V (1.1 V ≤ VCCB ≤ 5.5 V). |
