ISL3034E

6-Channel High Speed, Auto-direction Sensing Logic Level Translator

Product Status: Mass Production

OVERVIEW

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 VCC and VL supply voltages set the logic levels on either side of the device. Logic signals on the IC’s VL side appear as higher voltage logic signals on the IC’s VCC side. Logic signals on the IC’s VCC side appear as higher voltage logic signals on the IC’s VL 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 VCC or VL 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 VCC is less than VL .

The ISL3034E operates with VCC voltages from +2.2V to +3.6V and VL voltages from +1.35V to +3.2V, making it ideal for data transfer between low-voltage microcontrollers or ASICs and higher voltage components.
