The MAX3000E/MAX3001E/MAX3002–MAX3012 8-channel level translators provide the level shifting necessary to allow data transfer in a multivoltage system. 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 VCCside of the device, and vice-versa.
The MAX3000E/MAX3001E/MAX3002/MAX3003 use an architecture specifically designed to be bidirectional without the use of a directional pin.
The MAX3000E/MAX3001E/MAX3002/MAX3004–MAX3012 feature an EN input that, when low, reduces the VCC and VLsupply currents to < 2µA. The MAX3000E/MAX3001E also have ±15kV ESD protection on the I/O VCC side for greater protection in applications that route signals externally. The MAX3000E operates at a guaranteed datarate of 230kbps. The MAX3001E operates at a guaranteed data rate of 4Mbps. The MAX3002–MAX3012 operate at a guaranteed data rate of 20Mbps over the entire specified operating voltage range.
The MAX3000E/MAX3001E/MAX3002–MAX3012 accept VL voltages from +1.2V to +5.5V and VCC voltages from +1.65V to +5.5V, making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems. The MAX3000E/MAX3001E/MAX3002–MAX3012 are available in 20-bump UCSP™, 20-pin TQFN (5mm x 5mm), and 20-pin TSSOP packages.
