VS32X245

VS32X245 / VS32X2245 High Speed CMOS VSwitch 16-Bit Bus Switches Applications = = 5V to 3.3V translation in mixed-supply environment Hot-swap interface = = Logic replacement Bus isolation General Description The VS32X245 and VS32X2245 are high-speed TTL-compatible 16-bit bus switches in a flow-through pinout. Each device contains two banks of 8-bit switches with a common active-LOW enable (/OEx) for each bank. The low ON resistance of the VS32X245 allows inputs to be connected to outputs, without adding propagation delay and without generating additional signal noise. The VS32X2245 has 25Ω resistors in series with the switches to reduce ground-bounce noise from the driving source and signal reflection. The VS32X245 and VS32X2245 bus switches are function and pinout compatible with QS32X245 and QS32X2245 switches. They enable 5V to 3.3V translation when used with a diode in the power supply line. In addition, the high off-isolation in the ‘disable’ mode makes these switches ideal interface elements for hotswap applications. Features = = = = Enhanced N-FET with no DC path to VCC or GND in normal operating signal voltage range. Low impedance bidirectional data flow: 5Ω (VS32X245) and 25Ω (VS32X2245) Pin-compatible with QS32X245 and QS32X2245 switches. Near-zero propagation delay = = = = = = Zero added ground bounce or signal noise TTL-compatible control signals Undershoot clamp diodes on all switch and control pins ESD rating >2000V (Human Body Model) or >200V ...
