FSLV3245
Low Voltage Octal Bus Switch
General Description
The Fairchild Switch FSLV3245 provides 8-bits of high-
speed CMOS bus switching in a standard 245 pin-out. The
low On Resistance of the switch allows inputs to be con-
nected to outputs without adding propagation delay or gen-
erating additional ground bounce noise.
The device is organized as an 8-bit switch. 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-imped-
ance state exists between the two ports.
