description
The SN74CBTLV16800 provides 20 bits of
high-speed bus switching. The low on-state
resistance of the switch allows 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 device is organized as dual 10-bit bus switches with separate output-enable (OE) inputs. It can be used
as two 10-bit bus switches or one 20-bit bus switch. When OE is low, the associated 10-bit bus switch is on,
and port A is connected to port B. When OE is high, the switch is open, the high-impedance state exists between
the two ports, and port B is precharged to BIASV through the equivalent of a 10-k
resistor.
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.
The SN74CBTLV16800 is characterized for operation from –40
°
C to 85
°
C.
