TC7MB3245FK Description

Short technical summary and product information.

The Toshiba TC7MB3245FK is an octal bus switch designed for high-speed TTL-compatible applications. It provides eight bits of bus switching in a standard '245 device pinout, organized as one 8-bit switch. When the output enable (OE) is low, port A is connected to port B. When OE is high, the switch is open, creating a high-impedance state between the two ports.

 

Key electrical characteristics include an operating voltage range of 4.5V to 5.5V, a maximum propagation delay of 0.25 ns, and a typical on-resistance of 5 Ohms. The device also features ESD protection, with a human body model rating greater than ±2000V and a machine model rating greater than ±200V. All inputs are equipped with protection circuits against static discharge.

 

This bus switch is housed in a VSSOP (US20) package, making it pin-compatible with the 74xx245 type. It is functionally equivalent to the FST/CBT 3245. The operating temperature range is -40°C to 85°C. The low on-state resistance allows for connections with minimal propagation delay, making it suitable for various digital circuit designs.
