8.1 Overview

The SN74CBTLV1G125 device is a 1-channel 1:1 high-speed FET switch. The low ON-state resistance of the switch allows connections to be made with minimal propagation delay. The (OE) pin is an active low logic control pin that controls the data flow. The FET is disabled when the output-enable (OE) input is high. 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 VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
