The SN74CBTLV16210 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 SN74CBTLV16210 device is fully specified for partial-power-down applications using I
off. 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 SN74CBTLV16210 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.
