MAX3390EEUD+T

MAX3390EEUD+T is a ±15kV ESD-protected level translator. It provides the level shifting necessary to allow data transfer in a multi-voltage system. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. A low-voltage logic signal present on the VL side of the device appears as a high-voltage logic signal on the VCC side of the device, and vice-versa. This device accepts VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V, making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems. It is used in applications such as SPI, MICROWIRE, and I²C level translation, low-voltage ASIC level translation, smart card readers, cell-phone cradles, portable POS systems, portable communication devices, low-cost serial interfaces, cell phones, GPS, and telecommunications equipment.

• Operation down to +1.2V on VL, low power consumption reduces thermal dissipation
• Slew-rate limiting lowers EMI, protection features increase system reliability
• ±15kV ESD Protection on I/O VCC lines, thermal short-circuit protection
• Supply current from VCC is 130µA typical at (VCC = +3.3V, VL = +1.8V, TA = +25°C)
• VCC supply voltage range from 1.65V to 5.50V
• 1μA typical supply current in three-state output mode at (TA = +25°C)
• Propagation delay is 1.6µs maximum at (VCC = +3.3V, VL = +1.8V, TA = +25°C)
• Channel-to-channel skew is 500ns maximum at (VCC = +3.3V, VL = +1.8V, TA = +25°C)
• Maximum data rate is 230kbps minimum at (VCC = +3.3V, VL = +1.8V, TA = +25°C)
• Operating temperature range from -40°C to +85°C, 14-lead TSSOP package
