The UPD74HC125GS-E2 is a high-speed CMOS quad bus buffer gate with 3-state outputs manufactured by NEC. This device features four independent buffers, each with an output enable (OE) input. When OE is low, the output is enabled, and the buffer passes the input signal. When OE is high, the output is in a high-impedance state, effectively disconnecting the buffer from the bus. The device is designed for use in bus-oriented applications where multiple devices share a common bus.

Applications:

• Bus Interfacing
• Memory Addressing
• Data Multiplexing
• Line Driving
• Logic Level Translation

Features:

• Quad Buffer: Contains four independent buffer gates in a single package.
• 3-State Outputs: Provides high-impedance output state for bus isolation.
• High-Speed Operation: Low propagation delay ensures fast data transfer.
• Low Power Consumption: Minimizes energy usage, making it ideal for battery-operated devices.
• High Noise Immunity: Ensures reliable performance in noisy environments.
• Wide Operating Voltage: Operates effectively across a voltage range of 2V to 6V.

Benefits:

• Simplified Bus Management: 3-state outputs allow multiple devices to share a common bus without contention.
