FEATURES
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.
