SGM8T245S

The SGM8T245S is an 8-bit bus transceiver with configurable voltage translation and 3-state outputs. The An and Bn are 8-bit data input and output ports, DIR is the direction control input and OE is an output enable input. VCCA and VCCB are dual-supply pins. The supply voltage of VCCA and VCCB can range from 1.2V to 5.5V, making the device suitable for bidirectional translating among any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.5V voltage nodes. The An, DIR and OE pins are referenced to VCCA, and Bn pins are referenced to VCCB.

The direction control (DIR) input determines the direction of the data flow. The DIR (active high) enables data from An ports to Bn ports. The DIR (active low) enables data from Bn ports to An ports. When the output enable (OE) input is high, both An and Bn ports are disabled, so the buses are effectively isolated.

This device is highly suitable for partial power-down applications using power-off leakage current (IOFF) circuit. When the device is powered down, the current backflow will be prevented from passing through the device.
