Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OE | input | Active-LOW output enable input for buffer 1; when HIGH, output 1Y is put into the high-impedance (Z) OFF-state. |
| 2 | 1A | input | Data input for buffer 1; inputs include clamp diodes, and the input voltage range is 0 V to VCC. |
| 3 | 2Y | tri_state | 3-state data output of buffer 2; it is high-impedance when 2OE is HIGH. |
| 4 | GND | power_in | Ground reference (0 V); all voltages in the datasheet are referenced to GND. |
| 5 | 2A | input | Data input for buffer 2; inputs include clamp diodes, and the input voltage range is 0 V to VCC. |
| 6 | 1Y | tri_state | 3-state data output of buffer 1; it is high-impedance when 1OE is HIGH. |
| 7 | 2OE | input | Active-LOW output enable input for buffer 2; when HIGH, output 2Y is put into the high-impedance (Z) OFF-state. |
| 8 | VCC | power_in | Supply voltage, 2.0 V to 6.0 V for the 74HC2G125 (4.5 V to 5.5 V for the 74HCT2G125 variant). |
