The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as four 8-bit bus switches, two 16-bit bus switches, or one 32-bit bus switch. When output enable (/EN) is low, the switch is on and port A is connected to port B. When /EN is high, the switch is open and the high-impedance state exists between the two ports. APPLICATIONS INFORMATION Memory Interface - Solution for multiple memory devices on a bus Bus Isolation - Ability to electrically isolate a device, or banks of devices, from memory bus or ADC output when not needed - Enables bank switching for redundancy or device failure - Provides cold-sparing capability without the need for actual cold-sparing buffers Redundancy - Allows multiple non cold-spare devices to be present on a bus Supports Analog Applications - In voltage range: 3.0 to 3.6V or 4.5 to 5.5V - Signal isolation: -60dB - Bandwidth (3dB): 500 MHz 3A1 3B1 3A8 3B8 4A1 4A8 4B1 4B8 /EN4 /EN3 Figure 1.
