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 25
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 3.3V translation when used with a diode in the power supply line. In addition,
the high off-isolation in the ‘disable’ mode makes VS3244 and VS32244 ideal interface elements for hot-swap
applications.
