DESCRIPTION
This 10-bit bus switch is designed for 3 V to 3.6 V V
and SSTL_2 output enable (OE) input levels.
When OE is LOW, the 10-bit bus 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.
The low on-state resistance of the switch allows connections to be
made with minimal propagation delay.
The CBT3857 is characterized for operation from 0 C to +85 C.
