The QS32X245 provides a set of 16 high-speed CMOS TTL-compatible bus switches in a flow-through pinout. The low ON resistance of the QS32X245 allows inputs to be connected to outputs without adding propa-gation delay and without generating additional ground bounce noise. The Output Enable (OEn) signals turn the switches on similar to the OEn signal of the 74'245.
QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices.
The QS32X245 is characterized for operation at -40°C to +85°C.
