The SN74AVC1T45DBVT is a single-bit dual-supply non-inverting Bus Transceiver with configurable voltage-level shifting and three-state outputs. The SN74AVC1T45 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input activate either the B-port outputs or the A-port outputs. The device transmits data from the A-bus to the B-bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports always is active and must have a logic high or low level applied to prevent excess ICC and ICCZ. The SN74AVC1T45 is designed so that the DIR input is powered by VCCA. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

• Fully configurable dual-rail design
• DIR input circuit referenced to VCCA
• IOFF supports partial-power-down mode operation
• Latch-up performance exceeds 100mA per JESD 78
• ESD protection exceeds JESD 22
• Green product and no Sb/Br
