7.1 Overview

The SNx4ACT244 devices are buffer drivers with separate output enable inputs. The active low output enable sets the output to high impedance when a logic high is applied. For 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.
