5.0V, ±15kV ESD-Protected, Half-Duplex/Full-Duplex, RS-485 Transceiver in µDFN

The MAX13181E–MAX13184E are full-duplex and selectable half-/full-duplex RS-485 transceivers in a tiny 2mm x 2mm µDFN package. These devices are designed for space-constrained applications by including extended ESD protection to ±15kV per Human Body Model (HBM) and integrating pullup/pulldown resistors on the DE, active-low RE and H/active-low F inputs to reduce external components. The MAX13182E/MAX13184E feature a low-current shutdown mode for power-sensitive applications.

These devices have a 1/8 unit-load input receiver that allows up to 256 transceivers on the bus. The MAX13181E/MAX13182E feature reduced slew-rate drivers to minimize EMI and reflections that are caused by improperly terminated cables. The slew-rate limited MAX13181E/MAX13182E allow error-free data transmission up to 250kbps. The MAX13183E/MAX13184E feature full-speed drivers, allowing data rates of up to 16Mbps. The MAX13182E/MAX13184E are configured for full-duplex operation, while the MAX13181E/MAX13183E feature pin-selectable half- or full-duplex operation. All driver outputs and receiver inputs include extended ESD protection.

The MAX13181E–MAX13184E are available in a tiny 10-pin, 2mm x 2mm µDFN. The MAX13183E/MAX13184E are also available in industry-standard 14-pin SO packages. The devices operate over the extended -40°C to +85°C temperature range.
