RUNIC RS2T45XVS8-Q1

RS2T45-Q1 is a 2-bit non-inverting bus transceiver featuring two independently configurable supply rails. The A port and DIR pin are designed to track the VCCA supply, supporting an operating voltage range of 1.65V to 5.5V; the B port is designed to track the VCCB supply, also supporting 1.65V to 5.5V. This enables the device to provide universal low-voltage bidirectional level translation between 1.8V, 2.5V, 3.3V, and 5V voltage nodes. The RS2T45-Q1 is designed for asynchronous communication between two data buses. The logic level of the direction control input determines whether the B port output or the A port output is activated. When the B port output is activated, the device transfers data from the A bus to the B bus; when the A port output is activated, data is transferred from the B bus to the A bus. The input circuits of both the A and B ports are always active and must be driven to a logic high or low level to prevent excessive ICC and ICCZ currents. The RS2T45-Q1 is available in an eco-friendly VSSOP8 package with an operating ambient temperature range of -40°C to +125°C.
