The SN74CBT16245 provides 16 bits of high-speed TTL-compatible bus switching in a standard '16245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as two 8-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 a high-impedance state exists between the two ports. The SN74CBT16245 is characterized operation from 40C to 85C.
