WebDefinitions vary somewhat but a general guide to the voltage categories are as follows: Low Voltage (LV): up to 1000V. Medium Voltage (MV): between 1000 V and 45 kV. High Voltage (HV): between 45 kV and 230 kV. Extra High Voltage (EHV): from 230 kV and above. As a general rule, LV cables might be used in applications like fixed wiring; MV ... WebHEF4104BT - The HEF4104B is a quad low-to-high voltage translator with complementary 3-state outputs (Bn and Bn). A LOW on the output enable input (OE) causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VDD.
