QS3244QG - Renesas Electronics

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 ohm) of the 3244 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS3244 operates at -40C to +85C.
