This single-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVC1T45-Q1 is operational with VCCA/VCCB as low as 1.08V.

The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.08V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.08V to 3.6V. This allows for universal low-voltage, bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes.

The SN74AVC1T45-Q1 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-Q1 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.

The VCC isolation feature is designed so that if either VCC input is at GND, then both ports are in the high-impedance state.

NanoFree package technology is a major breakthrough in IC packaging concepts, using the die as the package.
