General Description
IDTQS3245 General Description
The QS3245 provides a set of eight high-speed CMOS TTL-compatible bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/LS245 8-bit transceivers. The low ON resistance of the QS3245 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The Output Enable (OE) signal turns the switches on similar to the OE signal of the 74'245.
QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices.
The QS3245 is characterized for operation at -40 to +85.
