CBT3244A

CBT3244A Octal bus switch with quad output enables Rev. 02 — 15 September 2005 Product data sheet 1. General description The CBT3244A 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 CBT3244A device 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. The CBT3244A is characterized for operation from −40 °C to +85 °C. 2.
