description

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 (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 a high-impedance state exists between the two ports.

The SN74CBT3244 is characterized for operation from 0°C to 70 °C.
