GENERAL DESCRIPTION
Externally applied voltages, VCC and VL, set the logic levels on either side of the device. Logic signals present on the VL side of the device appear as a higher voltage logic signal on the V CC side of the device and vice versa. The MAX13030E–MAX13035E operate at full speed with external 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 MAX13030E–MAX13035E to be driven by either pushpull or open-drain drivers. The MAX13030E–MAX13034E feature an enable (EN) input that places the device into a low-power shutdown mode when driven low. The MAX13030E–MAX13035E features an automatic shutdown mode that disables the part when V CC is less than VL. The state of I/O VCC_ and I/O VL_ during shutdown is chosen by selecting the appropriate part version (see Ordering Information/ Selector Guide). The MAX13030E–MAX13035E accept V CC voltages from +2.2V to +3.6V and VL voltages from +1.62V to +3.2V, making them ideal for data transfer between low-voltage ASIC/PLDs and higher voltage systems.
