• Quad bus switch with independent enable control for each channel.
• Low ON-state resistance allows for minimal signal distortion.
• High OFF-state isolation ensures signal integrity when channels are disabled.
• Wide supply voltage range enables compatibility with various systems.
• Fast switching speed supports high-speed data transmission.

Advantages and Disadvantages

Advantages of the 74CBTLV3125QG8 include:

• Versatile signal switching capability.
• Low power consumption.
• Compact QFN-20 package for space-constrained designs.
• High-speed data transmission.

Disadvantages of the 74CBTLV3125QG8 include:

• Limited number of channels (4 channels).
• Relatively higher cost compared to simpler switch ICs.

Working Principles

The 74CBTLV3125QG8 operates by selectively connecting or disconnecting the input/output channels based on the control signals received at the enable inputs (EN, OE1, OE2, OE3, OE4). When an enable signal is active, the corresponding channel is connected, allowing the passage of digital signals. When an enable signal is inactive, the channel is disconnected, providing high isolation between channels.
