MAX3093E/MAX3094E is a rugged, low-power, quad, RS-422/RS-485 receiver featuring electrostatic discharge (ESD) protection for use in harsh environments
The MAX3093E and MAX3094E are rugged, low‑power, quad RS‑422/RS‑485 receivers designed for harsh environments. They feature extensive ESD protection (±15 kV Human Body Model, ±8 kV Contact Discharge, ±15 kV Air‑Gap) and a fail‑safe output that defaults to a logic high when inputs are open.
Both devices are available in space‑saving 16‑pin TSSOP, narrow SO, and PDIP packages. The MAX3093E operates from a +5 V supply, while the MAX3094E runs from a +3.3 V supply. They support up to 128 receivers on a single bus and provide matched propagation‑delay tolerances of ±8 ns (MAX3093E) or ±10 ns (MAX3094E). This manual is written in Chinese.
