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 25
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.
