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 25
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 hot-
swap applications.
