Operation
description/ordering information
The SN74CBTLV1G125 features a single
high-speed line switch. The switch 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 V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
