Key Featrues

±15kV ESD Protection - The transceivers are protected against ±15kV electro-static discharge (ESD) shocks, ensuring robust performance in harsh environments and reducing the risk of damage from static electricity. This enhances reliability in industrial and EMI-sensitive applications.
Slew-Rate-Limited Drivers - Devices like the MAX483E and MAX487E feature reduced slew-rate drivers, minimizing EMI and reducing signal reflections on improperly terminated cables. This enables error-free data transmission up to 250kbps, making them ideal for noise-sensitive environments.
High-Speed Data Transmission - The MAX481E, MAX485E, and MAX1487E offer unlimited driver slew rates, allowing data transmission speeds up to 2.5Mbps. This makes them suitable for high-speed communication applications where rapid data transfer is critical.
Low-Power Operation - These transceivers are designed for low-power consumption, making them ideal for battery-powered or energy-efficient systems. This feature extends operational life and reduces power requirements in portable or remote applications.
Fail-Safe Receivers - Devices like the MAX3440E and MAX3483E include true fail-safe receivers, ensuring the output remains in a valid logic state even when the input is open, shorted, or idle. This enhances system reliability in fault-tolerant and industrial control networks.
