MAX3390EEUD+T

Translators, Level Shifters Overview

The MAX3390EEUD+T is a quad, unidirectional low-voltage level translator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a VCC supply range of +1.65V to +5.5V and a VL logic input range of +1.2V to +5.5V. The device supports data rates up to 16Mbps depending on voltage domains, featuring ±15kV ESD protection on I/O VCC lines and thermal short-circuit protection. It utilizes a three-state output mode to reduce quiescent current below 1μA. The component is housed in a 14-pin TSSOP package.
