SN74HCS126PWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OE | input | Schmitt-trigger input for Channel 1 output enable (active high); forces output to high-impedance when low. |
| 2 | 1A | input | Schmitt-trigger input for Channel 1 data input (0 to VCC); provides hysteresis for slow or noisy signals. |
| 3 | 1Y | tri_state | 3-state output for Channel 1 (Y=A when enabled); can sink/source 7.8mA at 6V. |
| 4 | 2OE | input | Schmitt-trigger input for Channel 2 output enable (active high); forces output to high-impedance when low. |
| 5 | 2A | input | Schmitt-trigger input for Channel 2 data input (0 to VCC); provides hysteresis for slow or noisy signals. |
| 6 | 2Y | tri_state | 3-state output for Channel 2 (Y=A when enabled); can sink/source 7.8mA at 6V. |
| 7 | GND | power_in | Ground; negative supply reference voltage (0V). |
| 8 | 3Y | tri_state | 3-state output for Channel 3 (Y=A when enabled); can sink/source 7.8mA at 6V. |
| 9 | 3A | input | Schmitt-trigger input for Channel 3 data input (0 to VCC); provides hysteresis for slow or noisy signals. |
| 10 | 3OE | input | Schmitt-trigger input for Channel 3 output enable (active high); forces output to high-impedance when low. |
| 11 | 4Y | tri_state | 3-state output for Channel 4 (Y=A when enabled); can sink/source 7.8mA at 6V. |
| 12 | 4A | input | Schmitt-trigger input for Channel 4 data input (0 to VCC); provides hysteresis for slow or noisy signals. |
| 13 | 4OE | input | Schmitt-trigger input for Channel 4 output enable (active high); forces output to high-impedance when low. |
| 14 | VCC | power_in | Positive supply voltage; operating range 2V to 6V per Recommended Operating Conditions. |
