VS3244 / VS32244 High Speed CMOS VSwitch Dual 4-Bit Bus Switches Applications •= •= 5V to 3.3V translation in mixed-supply environment Hot-swap interface •= •= Logic replacement Bus isolation General Description The VS3244 and VS32244 are high-speed TTL–compatible dual 4-bit bus switches. The VS3244 contains two banks of 4-bit switches, with one common active low enable (/G) per bank. The low ON resistance of the VS3244 allows inputs to be connected to outputs, without adding propagation delay and without generating additional signal noise. The VS32244 has 25Ω resistors in series with the switches to reduce ground-bounce noise and signal reflection. The VS3244 and VS32244 bus switches are function and pinout compatible with QS3244 and CBT3244 switches. They enable 5V to 3.
