DescriptionThis 8-bit noninverting bus transceiver uses two separate configurable power-supplyrails. The SN74AVC8T245PWE4 is optimized to operate withVCCA/VCCB set at 1.4 V to 3.6 V. The device isoperational with VCCA/VCCB as low as 1.2 V. The Aport is designed to track VCCA. VCCA accepts anysupply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB.VCCB accepts any supply voltage from 1.2 V to 3.6 V. This allows foruniversal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and3.3-V voltage nodes.
The SN74AVC8T245PWE4 is designed for asynchronous communication between data buses. Thedevice transmits data from the A bus to the B bus or from the B bus to the A bus, depending on thelogic level at the direction-control (DIR) input. The output-enable (OE shall be tied to VCC through a pullup resistor;the minimum value of the resistor is determined by the current-sinking capability of thedriver.
