Description

General part information

SN74CBT3126 Series

The SN74CBT3126 quadruple FET bus switch features independent line switches. Each switch is disabled when the associated output-enable (OE) input is low.

To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

The SN74CBT3126 quadruple FET bus switch features independent line switches. Each switch is disabled when the associated output-enable (OE) input is low.
