General Description

The RS2T45 is 2-bit non-inverting bus transceiver uses two separate configurable power supply rails.

The A port and DIR are designed to track VCCA, which supporting operating voltages from 1.65V to 5.5V, and the B port supporting operating voltages from 1.65V to 5.5V while it tracks the VCCB supply.

This allows for universal low-voltage bidirectional translation between any of the 1.8V, 2.5V, 3.3V and 5V voltage nodes.

Key Features

Control Input threshold Referenced to VCCA Voltage.
Power-Supply Range: VCCA and VCCB: 1.65V to 5.5V.
VCC Isolation: If Either VCC is at GND, Both Ports are in the High-Impedance State.
Low power consumption, 4uA Max.
Output drives up to ±24mA@3.0V.
No Power-Supply Sequencing Required: Either VCCA or VCCB can be Ramped First.
IOFF: Supports Partial-Power-Down Mode Operation.
Extended Temperature: -40°C to +125°C.
