FUNCTIONAL BLOCK DIAGRAM
LOW-VOLTAGE 20-BIT
BUS SWITCH WITH
PRECHARGED OUTPUTS
DESCRIPTION:
The CBTLV16800 provides 20-bits of high-speed bus switching with low
on-state resistance of the switch allowing connections to be made with
minimal propagation delay. The device also precharges the B port to a
user-selectable bias voltage (BIASV) to minimize live-insertion noise.
The CBTLV16800 is organized as dual 10-bit bus switches with two
different output-enable (
OE) control inputs. When OE is low, the corre-
sponding 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, and port B is precharged to BIASV through the equivalent
of a 10-k
Ω resistor.
To ensure the high-impedance state during power up or power down,
OE should be tied to VCC through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking capability of the driver.
