Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOIC-14
SN74LVC126AQDRQ1 from Texas Instruments, in a SOIC-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 | 1OE | input | Output enable for gate 1; when low, output 1Y is disabled and goes to high impedance. |
| 2 | 1A | input | Gate 1 input, which accepts 0 V to 5.5 V per the recommended operating conditions. |
| 3 | 1Y | tri_state | Gate 1 three-state output, which is high impedance when 1OE is low. |
| 4 | 2OE | input | Output enable for gate 2; when low, output 2Y is disabled and goes to high impedance. |
| 5 | 2A | input | Gate 2 input, which accepts 0 V to 5.5 V per the recommended operating conditions. |
| 6 | 2Y | tri_state | Gate 2 three-state output, which is high impedance when 2OE is low. |
| 7 | GND | power_in | Ground pin; the datasheet requires GND as the device reference. |
| 8 | 3Y | tri_state | Gate 3 three-state output, which is high impedance when 3OE is low. |
| 9 | 3A | input | Gate 3 input, which accepts 0 V to 5.5 V per the recommended operating conditions. |
| 10 | 3OE | input | Output enable for gate 3; when low, output 3Y is disabled and goes to high impedance. |
| 11 | 4Y | tri_state | Gate 4 three-state output, which is high impedance when 4OE is low. |
| 12 | 4A | input | Gate 4 input, which accepts 0 V to 5.5 V per the recommended operating conditions. |
| 13 | 4OE | input | Output enable for gate 4; when low, output 4Y is disabled and goes to high impedance. |
| 14 | VCC | power_in | Supply pin; the datasheet specifies an operating range of 1.65 V to 3.6 V and requires a bypass capacitor close to the pin. |
