2.5V/3.3V 8:1 Mux/Demux High Bandwidth Bus Switch
Jump to Page Section:
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 over-voltage tolerance makes the QS3VH251 ideal for high performance comminucation applications. The QS3VH251 operates from -40C to +85C.
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 - 4 ohm typical
- Flat RON characteristics over operating range
- Rail-to-rail switching 0 - 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
