Toshiba has introduced a pair of fast opto-couplers that will work from 2.2V, allowing them to work from the 2.5V rail of LVCMOS, for example, as well as up to 5.5V. Typical 3.3V data rates are: TLP2312 5Mbit/s TLP2372 20Mbit/s The threshold input current of 1.6mAmax and the supply current of 0.5mAmax at entire operating temperature ...
