5 Description continued

The SN74CB3Q16244 device is organized as four 4-bit bus switches with separate output-enable (1OE, 2OE,

3OE, 4OE) inputs. It can be used as four 4-bit bus switches, two 8-bit bus switches, or one 16-bit bus switch.

When OE is low, the associated 4-bit bus switch is ON, and the A port is connected to the B port, allowing

bidirectional data flow between ports. When OE is high, the associated 4-bit bus switch is OFF, and a high-

impedance state exists between the A and B ports.

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