Overview
Description
The QS3VH251 HotSwitch quad 2:1 multiplexer/demultiplexer is a high bandwidth bus switch with very low ON-resistance, resulting in under 250ps propagation delay through the switch. The combination of near-zero propagation delay, high OFF impedance, and overvoltage tolerance makes the QS3VH251 ideal for high-performance communication applications. The QS3VH251 operates from -40 °C to +85 °C.
Features
- N-channel FET switches with no parasitic diode to VCC
- Isolation under power-off conditions
- No DC path to VCC or GND
- 5V tolerant in OFF and ON state
- 5V tolerant I/Os
- Low RON - 4Ω typical
- Flat RON characteristics over operating range
- Rail-to-rail switching 0V to 5V
- Bidirectional dataflow with near-zero delay: No added ground bounce
- Excellent RON matching between channels
- VCC operation: 2.3V to 3.6V
- High bandwidth - Up to 500MHz
- LVTTL-compatible control Inputs
- Undershoot clamp diodes on all switch and control Inputs
- Low demux capacitance, 4pF typical
- Available in 16-pin QSOP and TSSOP packages
