DESCRIPTION:
The CBTLV32861 is a ten bit high-speed bus switch. It adds an
internal series resistor with each switch to reduce reflection noise in
high-speed applications. When closed, the switch acts as a source
(series) termination for the driver connected to it.
The device is organized as one 10-bit bus switch. When output
enable (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.
To ensure the high-impedance state during power up or power down,
OE
should be tied to V
CC
through a pullup resistor; the minimum value
of the resistor is determined by the current-sinking capability of the
driver.
