Key Features
- Quad 1-of-2 high-speed multiplexer/demultiplexer with common select (S) and output enable (OE) inputs.
- Low ON resistance of the switch, allowing connections with minimal propagation delay and no additional ground bounce noise.
- Schmitt trigger action at control inputs for tolerance to slower input rise and fall times across the entire VCC range.
- Support for partial-power-down mode operation with Ioff feature to prevent backflow current when powered down.
- Rail-to-rail switching on data I/O ports and latch-up performance exceeding 100 mA per JESD 78, Class II.
- High-impedance OFF-state during power-up or power-down when OE is tied to VCC through a pull-up resistor.
Applications
- Internet of Things (IoT) devices
- Wireless headphones and other audio equipment
- Television sets and other consumer electronics
- 4-bit bus multiplexing and demultiplexing in various digital systems
