FST3244
Octal Bus Switch
General Description
The Fairchild Switch FST3244 provides 8-bits of high-
speed CMOS TTL-compatible bus switching in a standard
’244 pin-out. The low on resistance of the switch allows
inputs to be connected to outputs without adding propaga-
tion delay or generating additional ground bounce noise.
The device is organized as two 4-bit switches with separate
OE inputs. When OE is LOW, the switch is ON and Port A
is connected to Port B. When OE is HIGH, the switch is
OPEN and a high-impedance state exists between the two
ports.
