VS32245

VS3245 / VS32245 High Speed CMOS VSwitch 8-Bit Bus Switches Applications = 5V to 3.3V translation in mixed-supply environment = Hot-swap interface = Logic replacement = Bus isolation General Description The VS3245 and VS32245 are high-speed TTL–compatible 8-bit bus switches. The VS3245 contains eight high-speed bus switches, with a common active low enable (/OE). The low ON resistance of the VS3245 allows inputs to be connected to outputs, without adding propagation delay and without generating additional signal noise. The VS32245 has 25Ω resistors in series with the switches to reduce ground-bounce noise and signal reflection. The VS3245 and VS32245 bus switches are function and pinout compatible with QS3245 and CBT3245 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 VS3245 and VS32245 ideal interface elements for hot-swap applications. Features = E...
