ISL3034E

The ISL3034E is a 6-channel bidirectional, auto-direction sensing, level translator that provides the required level shifting in multi-voltage systems at data transfer rates up to 100Mbps. The auto-direction sensing feature makes the ISL3034E ideally suited for generic six channel level translation especially if bit-by-bit direction control is desired. The V_CC and V_L supply voltages set the logic levels on either side of the device. Logic signals on the IC’s V_L side appear as higher voltage logic signals on the IC’s V_CC side. Logic signals on the IC’s V_CC side appear as higher voltage logic signals on the IC’s V_L side. The ISL3034E operates at full speed with external input drivers that source as little as 4mA output current. Each I/O channel is pulled up to V_CC or V_L by an internal 30μA current source, allowing the ISL3034E to be driven by either push-pull or open-drain drivers. Drive the ISL3034E’s enable (EN) input low to place the IC into a low-power shutdown mode with all I/O lines tri-stated. The device features an automatic shutdown mode that places the part in the same shutdown state when V_CC is less than V_L. The ISL3034E operates with VCC voltages from +2. 2V to +3. 6V and V_L voltages from +1. 35V to +3. 2V, making it ideal for data transfer between low-voltage microcontrollers or ASICs and higher voltage components.
