SN74ACT16PWR from Texas Instruments, 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 | 1A | input | Channel 1 Schmitt-trigger inverter input; TTL-compatible and must never be left floating, so unused inputs must be terminated at VCC or GND. |
| 2 | 1Y | output | Channel 1 open-drain output that can only drive low and needs an external pull-up (about 10kΩ is typical) to reach a high level. |
| 3 | 2A | input | Channel 2 Schmitt-trigger inverter input; TTL-compatible and must never be left floating, so unused inputs must be terminated at VCC or GND. |
| 4 | 2Y | output | Channel 2 open-drain output that can only drive low and needs an external pull-up (about 10kΩ is typical) to reach a high level. |
| 5 | 3A | input | Channel 3 Schmitt-trigger inverter input; TTL-compatible and must never be left floating, so unused inputs must be terminated at VCC or GND. |
| 6 | 3Y | output | Channel 3 open-drain output that can only drive low and needs an external pull-up (about 10kΩ is typical) to reach a high level. |
| 7 | GND | power_in | Ground reference; it must sink the total output current plus the maximum supply current, and the total GND current must not exceed the Absolute Maximum Ratings limit. |
| 8 | 4Y | output | Channel 4 open-drain output that can only drive low and needs an external pull-up (about 10kΩ is typical) to reach a high level. |
| 9 | 4A | input | Channel 4 Schmitt-trigger inverter input; TTL-compatible and must never be left floating, so unused inputs must be terminated at VCC or GND. |
| 10 | 5Y | output | Channel 5 open-drain output that can only drive low and needs an external pull-up (about 10kΩ is typical) to reach a high level. |
| 11 | 5A | input | Channel 5 Schmitt-trigger inverter input; TTL-compatible and must never be left floating, so unused inputs must be terminated at VCC or GND. |
| 12 | 6Y | output | Channel 6 open-drain output that can only drive low and needs an external pull-up (about 10kΩ is typical) to reach a high level. |
| 13 | 6A | input | Channel 6 Schmitt-trigger inverter input; TTL-compatible and must never be left floating, so unused inputs must be terminated at VCC or GND. |
| 14 | VCC | power_in | Positive supply; the recommended operating range is 4.5 V to 5.5 V and each VCC pin should have a bypass capacitor (0.1 µF recommended) placed close to the device. |
