GENERAL DESCRIPTION
Current sinking capability is 24 mA at both the A and B ports. Transmit (active-HIGH) enables data from A ports to B ports; Receive (active-LOW) enables data from B ports to A ports. The Output Enable input, when HIGH, disables both A and B ports by placing them in a HIGH Z condition. FEATURES
