Description

  The QS3244 provides a set of eight high-speed CMOS TTL-compatible bus switches in a pinout compatible with 74FCT244, 74F244, 74ALS/AS/LS244 8-bit drivers. The low ON resistance (5) of the 3244 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The two enable (xG) signals turn the switches on similar to the xG signals of the 74'244.

  QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices.

  The QS3244 is characterized for operation at -40°C to +85°C.
