Flip-Chip TSSOP Externally applied voltages, VCC and VL, set the logic levels on either side of the device. It utilizes a transmission-gate-based design to allow data translation in either direction (VL <-> VCC) on any single data line. The ST2378E accepts VL from +1.71V to VCC and VCC from +1.71V to +5.5V, making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems. The ST2378E has a three-state output mode that reduces supply current to less than 1µA, thermal short-circuit protection, and ±15kV ESD protection on the VCC side for greater protection in applications that route signals externally. The ST2378E operates at a guaranteed data rate of 13Mbps over the entire specified operating voltage range. Within specific voltage domains, higher data rates are possible.
