onsemi NL3V1T244/34 1-Bit Dual-Supply Level Translators
onsemi NL3V1T244 and NL3V1T34 1-Bit Dual-Supply Level Translators are designed to provide reliable, high‑speed, non‑inverting voltage translation between two independent power domains. Each device supports dual supply rails, VCCA and VCCB, both configurable from 0.9V to 3.6V, enabling flexible translation for a wide range of low‑voltage digital interfaces. The translators track the respective supply rails, ensuring proper logic‑level compatibility across different system voltages. The NL3V1T244 includes a 3‑state output enable (OE) pin that disables the output when driven high, while the NL3V1T34 provides similar non‑inverting translation functionality but without an OE pin, offering a simpler interface.
The compact onsemi NL3V1T244 and NL3V1T34 devices feature high‑speed operation with balanced propagation delays, input overvoltage tolerance up to 3.6V, and robust behavior during power sequencing, including outputs that remain in 3‑state until active supply levels are reached. The components also include partial power‑off protection, ensuring outputs switch to high‑impedance when either supply rail is grounded. With support for data rates up to 380Mbps (depending on translation conditions), along with ultra‑small SC‑88A and UDFN6 package options, these translators are well‑suited for mobile, portable, automotive, and industrial applications requiring efficient, low‑voltage logic‑level shifting.
