SN74LV1T125DBVR Pin Configuration
SN74LV1T125DBVR Pinout
Package: SC-74A (SOT-753), 5-pin
| Pin Number | Pin Name | Type | Description |
|---|---|---|---|
| 1 | OE | I | Output enable, active low |
| 2 | A | I | Input A |
| 3 | GND | G | Ground |
| 4 | Y | O | Output Y |
| 5 | VCC | P | Positive supply |
Notes
- This is a single-gate buffer/driver with tri-state output control.
- OE (pin 1) is active low; when OE = 0, output Y follows input A; when OE = 1, output is high-impedance.
- Pin 3 is ground; pin 5 is positive supply voltage.
