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.Read more
