The SN74AVC1T45DRLR is a single-bit dual-supply Bus Transceiver with configurable voltage-level shifting and 3-state outputs. It uses two separate configurable power-supply rails. It is optimized to operate with VCCA/VCCB set at 1.4 to 3.6V. It is operational with VCCA/VCCB as low as 1.2V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 to 3.6V. It 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.

• Fully configurable dual-rail design
• VCC Isolation feature - If either VCC input is at GND, both ports are in the high-impedance state
• DIR Input circuit referenced to VCCA
• ±12mA Output drive at 3.3V
• I/Os Are 4.6V tolerant
• Ioff Supports partial-power-down mode operation
• Green product and no Sb/Br
