Switch
Connection Between Two Ports
The SN74CBT3244 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 device is organized as two 4-bit low-impedance switches with
separate output-enable (
)
inputs. When is low, the
switch is on and data can flow from port A to port B, or vice versa.
When is high, the
switch is open and a high-impedance state exists between the two
ports.
The SN74CBT3244 is characterized for operation from 0°C to 70 °C.
