Datasheet

Maxim introduced the MAX14548E/MAX14548AE, ±15kV ESD-protected, 16-channel, bidirectional level translators. These devices provide level shifting for data transfer in multivoltage systems by accepting a voltage range from 1.1V to 3.6V on the VL side and from 1.7V to 3.6V on the ±15kV ESD-protected Vcc side. Over these specified operating voltages, the MAX14548E/ MAX14548AE operate at a guaranteed data rate of 100Mbps. The low supply voltage, small wafer-level package (WLP), and ESD protection make these level translators ideal for data transfer between low-voltage ASICs/programmable logic devices (PLDs) and higher-voltage systems such as camera modules, NAND flash memory, and LCD displays.

The MAX14548E/MAX14548AE feature a power-saving shutdown mode that forces the I/O lines to a high-impedance state and decreases the supply current to less than 1microamp (typ). These level translators are compatible with 4mA input open-drain or push-pull drivers, which makes them suitable for a wide variety of applications.

Fully specified over the -40 degrees Celsius to +85 degrees Celsius extended-temperature range, the MAX14548E/MAX14548AE are packaged in a 2.16mm x 3.46mm, 40-bump WLP.
