IDTQS3VH253 2.5V / 3.3V DUAL 4:1 MUX/DEMUX HIGH BANDWIDTH BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS 2.5V / 3.3V DUAL 4:1 MUX/DEMUX HIGH BANDWIDTH BUS SWITCH IDTQS3VH253 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 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 I/O capacitance, 4pF typical Available in QSOP and TSSOP packages APPLICATIONS: Hot-swapping Multiplexing/demultiplexing Low distortion analog switch Replaces mechanical relay ATM 25/155 switching FUNCTIONAL BLOCK DIAGRAM S0 S1 EA EB DESCRIPTION: The QS3VH253 HotSwitch Dual 4:1 multiplexer/demultiplexer is a high bandwidth bus switch. The QS3VH253 has very low ON resistance, resulting in under 250ps propagation delay through the switch. The Select (Sx) inputs control the data flow. The multiplexers/demultiplexers are enabled when the Enable (EA, EB) inputs are low. In the ON state, the switches can pass signals up to 5V. In the OFF state, the switches offer very high impedance at the terminals. The combination of near-zero ...
