Product Summary

The cbt3244apw is an Octal bus switch with quad output enables. It provides eight bits of high-speed TTL-compatible bus switching in a standard 244 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The cbt3244apw is organized as two 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 high-impedance state exists between the two ports.

Parametrics
