Additional Details:

The 74VHCT126AFT(BE) comprises four independent buffer/line driver circuits, each equipped with a three-state output. The output enable (OE) input governs the output state; a low OE signal enables the output, while a high OE signal puts the output in a high-impedance state. This feature makes the device ideal for applications involving shared buses.

The device operates within a temperature range of -40°C to +85°C.
