QUICKSWITCH
8-BIT BUS SWITCH
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
Ω) 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.
