description
The SN74CBTLV16211 provides 24 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 is organized as dual 12-bit bus
switches with separate output-enable (OE)
inputs. It can be used as two 12-bit bus switches
or one 24-bit bus switch. When OE is low, the
associated 12-bit bus switch is on and port A is
connected to port B. When OE is high, the switch
is open, and the 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
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.
