DESCRIPTION
The CBT3244 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 CBT3244 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 CBT3244 is characterized for operation from –40 to 85
°C.
