74HCT126PW
Nexperia · Buffers, Drivers, Receivers, Transceivers · TSSOP-14
74HCT126PW from Nexperia, 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 | 1OE | input | Data enable input for buffer 1, active HIGH; a LOW level puts output 1Y into the high-impedance OFF-state. |
| 2 | 1A | input | Data input for buffer 1; the input has clamp diodes, and the recommended input voltage range is 0 V to VCC. |
| 3 | 1Y | tri_state | Data output for buffer 1 with 3-state capability; the output is high-impedance when 1OE is LOW. |
| 4 | 2OE | input | Data enable input for buffer 2, active HIGH; a LOW level puts output 2Y into the high-impedance OFF-state. |
| 5 | 2A | input | Data input for buffer 2; the input has clamp diodes, and the recommended input voltage range is 0 V to VCC. |
| 6 | 2Y | tri_state | Data output for buffer 2 with 3-state capability; the output is high-impedance when 2OE is LOW. |
| 7 | GND | power_in | Ground (0 V) reference for all voltages on the device. |
| 8 | 3Y | tri_state | Data output for buffer 3 with 3-state capability; the output is high-impedance when 3OE is LOW. |
| 9 | 3A | input | Data input for buffer 3; the input has clamp diodes, and the recommended input voltage range is 0 V to VCC. |
| 10 | 3OE | input | Data enable input for buffer 3, active HIGH; a LOW level puts output 3Y into the high-impedance OFF-state. |
| 11 | 4Y | tri_state | Data output for buffer 4 with 3-state capability; the output is high-impedance when 4OE is LOW. |
| 12 | 4A | input | Data input for buffer 4; the input has clamp diodes, and the recommended input voltage range is 0 V to VCC. |
| 13 | 4OE | input | Data enable input for buffer 4, active HIGH; a LOW level puts output 4Y into the high-impedance OFF-state. |
| 14 | VCC | power_in | Supply voltage; 4.5 V to 5.5 V recommended for 74HCT126, with an absolute maximum of 7 V. |
