description/ordering information
The SN74CBTLV16210 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 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 as 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, and the high-impedance state exists
between the two ports.
This device is fully specified for
partial-power-down applications using I_off. The I_off
feature ensures that damaging current will not
backflow through the device when it is powered
down. The device has isolation during power off.

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.
