IDTQS3VH251 INDUSTRIAL TEMPERATURE RANGE 2.5V / 3.3V QUAD 8:1 MUX/DEMUX HIGH BANDWIDTH BUS SWITCH IDTQS3VH251 QUICKSWITCH PRODUCTS 2.5V / 3.3V 8:1 MUX / DEMUX HIGH BANDWIDTH BUS SWITCH FEATURES: DESCRIPTION: N channel FET switches with no parasitic diode to VCC The QS3VH251 HotSwitch Quad 2:1 multiplexer/demultiplexer is a high Isolation under power-off conditions bandwidth bus switch. The QS3VH251 has very low ON resistance, No DC path to VCC or GND resulting in under 250ps propagation delay through the switch. The Select 5V tolerant in OFF and ON state (Sx) input controls the data flow. The multiplexers/demultiplexers are 5V tolerant I/Os enabled when the Enable (E) input is low. In the ON state, the switches can Low RON - 4 typical pass signals up to 5V. In the OFF state, the switches offer very high Flat RON characteristics over operating range impedence at the terminals. Rail-to-rail switching 0 - 5V The combination of near-zero propagation delay, high OFF impedance, Bidirectional dataflow with near-zero delay: no added ground and over-voltage tolerance makes the QS3VH251 ideal for high perfor- bounce mance comminucation applications. Excellent RON matching between channels The QS3VH251 is characterized for operation from -40C to +85C. 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 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 S2 E I0 I1 I2 I3 Y I4 I5 I6 I7 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
