MAX3390EEUD

The Analog Devices MAX3390EEUD is a dual low-voltage level translator that facilitates data transfer in multivoltage systems. It allows logic signals to shift between different voltage domains, with externally applied voltages VCC and VL setting the logic levels. This device accepts VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V, making it suitable for interfacing low-voltage ASICs/PLDs with higher voltage systems.

Key features include a guaranteed data rate of 8Mbps over the specified operating voltage range, Tri-State output mode for reduced supply current (<1μA), and ±15kV ESD protection on the VCC side. The MAX3390EEUD is designed for unidirectional level translation and operates over a temperature range of -40°C to 85°C.

This level translator is available in a 14-TSSOP package with a surface mount type. Its design simplifies system integration by enabling data transfer between lower and higher voltage systems, reducing EMI emissions through slew-rate limiting, and increasing system reliability with thermal short-circuit protection.

Applications include SPI, MICROWIRE, and I2C level translation, low-voltage ASIC level translation, smart card readers, cell-phone cradles, portable POS systems, and telecommunications equipment.
