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.
