DESCRIPTION/ORDERING INFORMATION

SN74CBTLV1G125

LOW-VOLTAGE SINGLE FET BUS SWITCH

SCDS057H – MARCH 1998 – REVISED JUNE 2006

• 5- Ω Switch Connection Between Two Ports • I

off

Supports Partial-Power-Down Mode

Operation

• Rail-to-Rail Switching on Data I/O Ports

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

through a pullup

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