- Features low 180 µA supply current at 3.3 V with current shutdown mode reducing consumption to less than 2 µA
- Offers up to 20 Mbps data rate, fast propagation delay and excellent package-to-package skew times for improved operation in clock distribution systems
- Includes ±15 kV ESD protection and +125 °C operation making them ideal for harsh industrial environments
Exar Corporation announced a family of high-speed RS-485/RS-422 transmitters that combine low power, high performance, small packaging and high ±15 kV ESD protection. This family is best suited for industrial applications such as multi-drop clock distribution, telecom networking, robotic control, process automation and local area network applications.
The XR33193, XR33194 and XR33195 operate from a 3.3 V supply and draw only 180 µA (375 µA maximum) of supply current. All transmitters feature a shutdown mode that consumes less than 2 µA 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 3 mm × 3 mm footprint and feature 250 kbps, 2.5 Mbps and 20 Mbps 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 25 ns propagation delay and 5 ns driver-output skew. All three RS-485 transmitters feature ±15 kV 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.
Pricing and Availability:
The XR33193, XR33194 and XR33195 are available now in an RoHS compliant and green TSOT23-6 packages. Pricing starts at $0.55 in quantities of 1,000.
