LOW-VOLTAGE 10-BIT
BUS SWITCH
DESCRIPTION:
The CBTLVR3384 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 dual 5-bit bus switches with separate output-
enable (
OE) inputs, to allow use as two 5-bit bus switches or one 10-bit bus
switch. When
OE is low, the associated 5-bit bus switch is on and A port is
connectedtoBport.When
OEishigh,theswitchisopen,andahigh-impedance
state exists between the two ports.
To ensure the high-impedance state during power up or power down,
OE
shouldbetiedtoVCCthroughapullupresistor;theminimumvalueoftheresistor
is determined by the current-sinking capability of the driver.
