TC7MBD3244AFK Datasheet Octal Bus Switch

Manufacturer: Toshiba

Overview: TC7MBD3244AFK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MBD3244AFK Octal Bus Switch The TC7MBD3244AFK provides eight bits of high-speed TTL-compatible bus switching in a standard ’244 device pinout. The low on 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 device is enable to realize the shift of signal level from 5 V to 3.3 V. All inputs are equipped with protection circuits against static discharge. Weight: 0.03 g (typ.
