Description

The IDTQS3R245 provides a set of eight high-speed CMOS TTL-compatiblebus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/LS245 8-bit transceivers. The low ON resistance of the IDTQS3R245 allowsinputs to be connected to outputs without adding propagation delay andwithout generating additional ground bounce noise. The Output Enable (OE)signal turns the switches on similar to the OE signal of the 74'245. The lowON resistance of QS3R245 makes it ideal for PCI hot docking applications.

QuickSwitch devices provide an order of magnitude faster speed thanconventional logic devices.

The IDTQS3R245 is characterized for operation at -40 to +85.
