Description
The HD74CBT3244 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 the high impedance state exists between the two ports.
Features
• Standard ’244 type pinout.
• Minimal propagation delay through the switch.
• 5 Ω switch connection between two ports.
• TTL-compatible input levels.
• Ultra low quiescent power.
-Ideally suited for notebook applications.
