The MAX3372E–MAX3379E and MAX3390E–MAX3393E are bidirectional level translators that provide the necessary level shifting for data transfer in a multivoltage system. They are ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems, and feature a three-state output mode, thermal short-circuit protection, and ±15kV ESD protection.
The MAX3372E‑MAX3379E and MAX3390E‑MAX3393E families are +15 kV ESD‑protected low‑voltage level translators that shift data between multivoltage systems. They support bidirectional or unidirectional translation depending on the part, with VL input ranges from 1.2 V to 5.5 V and VCC ranges from 1.65 V to 5.5 V.
Key features include guaranteed data‑rate options from 230 kbps up to 16 Mbps, three‑state output with ultra‑low 1 pA quiescent current, thermal short‑circuit protection, and a variety of package options such as 3 × 3 UCSP, 8‑pin TDFN, 8‑pin SOT23‑8, 3 × 4 UCSP, 14‑pin TDFN, and 14‑pin TSSOP. Absolute maximum ratings, electrical characteristics, timing data, and package dimensions are provided in the following sections.
