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
connected to B port. 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.
APPLICATIONS:
• 3.3V High Speed Bus Switching and Bus Isolation

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

NOTES:
1. Typical values are at 3.3V, +25°C ambient.
2. The increase in supply current is attributable to each input that is at the specified voltage level rather than V
CC
or GND.
3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined by the lower of the voltages
of the two (A or B) terminals.
