FSLV34X245QSP
FSLV34X245
32-Bit Bus Switch (Preliminary)
General Description
The Fairchild Switch FSLV34X245 provides 32-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 32-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.
