DescriptionThis 4-bit noninverting bus transceiver uses two separate configurable power-supplyrails. The A port is designed to track VCCA. VCCAaccepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to trackVCCB. VCCB accepts any supply voltage from 1.2 to 3.6V. The SN74AVC4T774RSVR is optimized to operate withVCCA/VCCB set at 1.4 V to 3.6 V. It is operationalwith VCCA/VCCB as low as 1.2 V. This allows foruniversal low-voltage bi-directional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and3.3-V voltage nodes.
The SN74AVC4T774RSVR is designed for asynchronous communication between data buses. The logiclevels of the direction-control (DIR) input and the output-enable (OE should be tied to VCCA through a pullup resistor;the minimum value of the resistor is determined by the current-sinking capability of the driver.Since this device has CMOS inputs, it is very important to not allow them to float. If the inputsare not driven to either a high VCC state, or a low-GND state, anundesirable larger than expected ICC current may result. Since the inputvoltage settlement is governed by many factors (for example, capacitance, board-layout, packageinductance, surrounding conditions, and so forth), ensuring that they these inputs are kept out oferroneous switching states and tying them to either a high or a low level minimizes theleakage-current.
