8-BIT BUS SWITCH

DESCRIPTION:

bus switches in a pinout compatible with 74FCT244, 74F244, 74ALS/AS/

LS244 8-bit drivers. The low ON resistance (5Ω) 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.

conventional logic devices.

The QS3244 provides a set of eight high-speed CMOS TTL-compatible

QuickSwitch devices provide an order of magnitude faster speed than

PRODUCTS

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