RS1T45 1-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs FEATURES • • • • • • • • DESCRIPTION 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, 4µA Max Output drive 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 APPLICATIONS • • • • Industrial Enterprise Telecom, such as VOIP Personal electronic The RS1T45 is 1-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. The RS1T45 is designed for asynchronous communication between two data buses. The logic levels of the directioncontrol (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 is always active on both A and B ports and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ. The RS1T45 is available in Green SOT23-6 and SC70-6 packages. It operates over an ambient temperature range of -40°C to +125°C.
