Additional Details:

The 74VHCT125AFT(BE) features four independent buffer/line driver circuits, each with a three-state output. The output enable (OE) input controls the output state. When OE is low, the output is enabled, and when OE is high, the output is in a high-impedance state. The device is ideal for applications where multiple devices share a common bus.

The operating temperature range is -40°C to +85°C.
