The HD74LVC125ATELL-E is a quad bus buffer gate with 3-state outputs manufactured by Renesas Electronics. It belongs to the 74LVC family, which is characterized by its low voltage operation and high-speed performance. This device consists of four independent buffer gates, each with its own output enable (OE) input. When the OE input is low, the buffer is enabled, and the input signal is passed to the output. When the OE input is high, the output is disabled, entering a high-impedance state. This allows multiple devices to share a common bus, enabling tri-state logic functionality.
