Description

The IDTQS3388 provides ten high-speed CMOS TTL-compatible bus switches with active terminators on the bus switch I/O pins. The low ON resistance (5) of the 3388 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. When the switches are turned off, a low drive active terminator circuit drives the disconnected pins to VCC or ground, away from the TTL threshold. This prevents undriven buses from floating. The Bus Enable (BE) signal turns the switches on. The Bus Exchange (BX) signal provides nibble swap of the AB and CD pairs of signals. This exchange configuration allows byte swapping of buses in systems. It can also be used as a five-wide 2-to-1 multiplexer and to create low delay barrel shifters, etc.

The IDTQS3388 is characterized for operation at -40°C to +85°C.
