This device can be used for memory bank interleaving. The Near-Zero Propagation Delay PI3B16233 can be used as two 8-bit to 16-bit multiplexers or as one Fast Switching Speed: 4.5ns (max.) 16-bit to 32-bit multiplexer. Ultra -Low Quiescent Power (0.2mA typ.) Two select inputs (SEL1 and SEL2) control the data flow. When the Ideal for notebook applications. TEST inputs are asserted HIGH, the A port is connected to both the Industrial Operating Temperature: 40C to 85C B1 and the B2 ports.
