Description
The HD74CBT3245A provides eight bits of high speed TTL-compatible bus switching in a standard ’245
device pinout. The low on state resistance of the switch allows connections to be made with minimal
propagation delay. The device is organized as one 8-bit switch. When output enable (OE) is low, the
switch is on, and port A is connected to port B. When OE is high, the switch is open, and the high
impedance state exists between the two ports.
Features
• Standard ’245 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.
