DESCRIPTION/ORDERING INFORMATION (CONTINUED)

The SN74CB3T16210 is organized as two 10-bit bus switches with separate ouput-enable (1OE, 2OE) 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 the A port is connected to the B port, allowing bidirectional data flow between ports. When OE

is high, the associated 10-bit bus switch is OFF, and a high-impedance state exists between the A and B ports.

This device is fully specified for partial-power-down applications using Ioff. The Ioff 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 VCC through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
