This 16-bit (dual-octal) noninverting bus transceiver has two distinct supply rails. B port has a VCCB that is programmed to run at 3.3 V and 5 V. A port includes VCCA, which is configured to run at 2.5 V and 3.3 V. This enables translation from a 2.5-V to a 3.3-V environment and back, as well as from a 3.3-V to a 5-V environment. The SN74ALVC164245 is intended for asynchronous communication between data buses. The control circuitry (1DIR, 2DIR, 1OE, and 2OE) is supplied by VCCA. To maintain the high-impedance condition during power up or power down, connect the output-enable (OE) input to VCC via a pullup resistor; the minimum value of the resistor is specified by the driver's current-sinking capabilities. The logic levels of the direction-control (DIR) and output-enable (OE) inputs activate either the B-port or A-port outputs, or both output ports are switched to high impedance mode. When the B-port outputs are turned on, the device sends data from the A bus to the B bus, and when the A-port outputs are turned on, data is sent from the B bus to the A bus. To prevent superfluous ICC and ICCZ, the input circuitry on both A and B ports is constantly active and must be set to logic HIGH or LOW.
