Translators and Level Shifters

Translator and Level Shifter ICs are digital interface logic devices designed to convert digital signal voltage levels between different logic domains, enabling seamless communication between processors, memory chips, and peripherals operating on different supply voltages (such as 1.2V, 1.8V, 2.5V, 3.3V, and 5V). Level shifters protect low-voltage sub-micron processors from overvoltage damage and ensure correct logic threshold detection.

Level shifters are available in unidirectional, bidirectional with direction control pins, and auto-sensing bidirectional configurations (such as TI's TXS and TXB series or Nexperia's NTS series) that automatically determine data direction without a control signal. Key selection parameters include channel count (1-bit to 32-bit), maximum data speed (Mbps), propagation delay, and Ioff partial-power-down protection to prevent leakage currents when one rail is powered down.
