IDTQS32XVH2245 INDUSTRIAL TEMPERATURE RANGE 2.5V / 3.3V 16-BIT HIGH BANDWIDTH BUS SWITCH QUICKSWITCH PRODUCTS IDTQS32XVH2245 2.5V / 3.3V 16-BIT HIGH BANDWIDTH BUS SWITCH FEATURES: DESCRIPTION: N channel FET switches with no parasitic diode to VCC The QS32XVH2245 HotSwitch is a high bandwidth, 16-bit bus switch. The Isolation under power-off conditions QS32XVH2245, with 25 ON resistance and 1.35ns propagation delay, is No DC path to VCC or GND ideal for line matching and low noise environments. The switches can be turned 5V tolerant in OFF and ON state ON under the control of the LVTTL-compatible Output Enable (OEx) signal for 5V tolerant I/Os bidirectional data flow with no added delay or ground bounce. In the ON state, Flat RON characteristics over operating range the switches can pass signals up to 5V. In the OFF state, the switches offer very Rail-to-rail switching 0 - 5V high impedence at the terminals. Bidirectional dataflow with near-zero delay: no added ground The combination of small propagation delay, high OFF impedance, and bounce over-voltage tolerance makes the QS32XVH2245 ideal for hot-swapping Excellent RON matching between channels applications. VCC operation: 2.3V to 3.6V The QS32XVH2245 is characterized for operation from -40C to +85C. High bandwidth LVTTL-compatible control Inputs Undershoot Clamp Diodes on all switch and control Inputs Low I/O capacitance, 4pF typical 25 resistors for low noise and line matching Available in 40-pin QVSOP package APPLICATIONS: Hot-swapping Low distortion analog switch Replaces mechanical relay ATM 25/155 switching FUNCTIONAL BLOCK DIAGRAM A0 A1 A2 A3 A4 A5 A6 A7 OE1 B0 B1 B2 B3 B4 B5 B6 B7 A8 A9 A10 A11 A12 A13 A14 A15 OE2 B8 B9 B10 B11 B12 B13 B14 B15 INDUSTRIAL TEMPERATURE RANGE JUNE 2011 1 c DSC-5777/14IDTQS32XVH2245 2.5V / 3.3V 16-BIT HIGH BANDWIDTH BUS SWITCH INDUSTRIAL TEMPERATURE RANGE (1) ABSOLUTE MAXIMUM RATINGS PIN CONFIGURATION Symbol Description Max Unit (2) VTERM SupplyVoltage to Ground 0.5 to +4.6 V (3) VTERM DC Switch Voltage VS 0.5 to +5.5 V 1 NC 40 VCC (3) VTERM DC Input Voltage VIN 0.5 to +5.5 V 39 2 A0 OE1 VAC AC Input Voltage (pulse width 20ns) 3 V 38 A1 3 B0 IOUT DC Output Current (max. sink current/pin) 120 mA 4 A2 37 TSTG Storage Temperature 65 to +150 C B1 5 36 NOTES: A3 B2 1.
