RS-485 Transmitters support 20Mbps, draw under 0.6mW

Exar's novel family of high-speed RS-485/RS-422 transmitters combine low power, high performance, small packaging and high ±15kV ESD protection.

The XR33193, XR33194 and XR33195 operate from a 3.3V supply and draw only 180µA (375µA maximum) of supply current.  All transmitters feature a shutdown mode that consumes less than 2µA whenever the transmitters are disabled.  The family is available in tiny 6-pin TSOT23 packages, ideal for high-speed point-to-point RS-485 applications where space is a concern. 
The XR33193/94/95 occupy a 3x3mm footprint and feature 250kbps, 2.5Mbps and 20Mbps data rates. The XR33193 and XR33194 have slew-limited outputs for reduced EMI and error-free communication over long or improperly terminated data cables and multi-drop applications with unterminated stubs. The XR33195 features fast 25ns propagation delay and 5ns driver-output skew. All three RS-485 transmitters feature ±15kV ESD protection on the driver outputs and operate over an extended temperature range of -40°C to +125°C.  They also offer hot-swap glitch protection allowing live insertion without driving invalid data onto shared busses.
