description/ordering information
The SN74CBTLV16211C 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 as 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.
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.
