16-Bit FET Bus Switch

The 'CBT16244 devices provide 16 bits of high-speed TTL-compatible bus switching in a standard '16244 device pinout. The low on-state resistance of the Switch allows connections to be made with minimal propagation delay.
These devices are organized as four 4-bit low-impedance switches with separate output-enable (OE) inputs. When OE is low, the Switch is on, and data CAN flow from port A to port B, or vice versa. When OE is high, the Switch is open, and the high-impedance state exists between the two ports.
