implementation
74AHC1G125 = SINGLE BUFFER GATE WITH 3-STATE OUTPUT
The 74AHC1G125 is a single non-inverting buffer/bus driver with a 3-state output. The output enters a high impedance state when a HIGH-level is applied to the output enable (OE) pin. The device is designed for operation with a power supply range of 2.0V to 5.5V.

SN74AHC1G08
SN74AHC1G08 Single 2-Input Positive-AND Gate
The SN74AHC1G08 device is a single 2-input positive-AND gate. The device performs the Boolean function
Y = A ● B
or Y = A + B
in positive logic.

| 1 | 1 | 1 |
| Term | Meaning |
|---|---|
| AND gate | Basic logic gate: output is 1 only if both inputs are 1 |
| Positive-AND gate | Same thing — "positive" means using standard logic levels (high = 1) |
| Negative logic | Less common, where high voltage = logic 0 |
