XR33193/XR33194/XR33195 3.3V, 20Mbps, TSOT23 RS-485/RS-422 Transmitters with 15kV ESD Protection Description FEATURES The XR33193, XR33194, and XR33195 are a high performance Date rate options of 250kbps, 2.5Mbps RS-485/RS-422 driver family offered in a tiny TSOT23 package and 20Mbps Tiny 6-pin TSOT23 package designed to meet the increasing system requirements found in todays 3.3V 5% supply operation performance serial communication applications. These standalone Robust ESD protection drivers operate off a single 3.3V supply and meet RS-485 and RS-422 15kV Human Body Model (bus pins) standards for balanced RS-485 and RS-422 serial communications 4kV Human Body Model (all other networks. pins) Short-circuit protection The driver family offers several speed options to maximize performance Thermal protection circuitry in different applications. The XR33193 and XR33194 have slew limited Hot swap glitch protection outputs for reduced EMI and for error free communication over long Extended -40C to 125C operating or improper/unterminated data cables or multi-drop applications with temperature range unterminated stubs. The XR33195 driver operates at data rates up to Low current shutdown mode (2uA max) 20Mbps with tight skew and prop delay specs required by demanding Lead-free (RoHS compliant) high speed applications. All parts in the XR33193/94/95 driver family operate over the extended temperature range of -40C to 125C. APPLICATIONS Clock distribution The XR33193/94/95 driver family is protected by short-circuit detection Robotic control as well as thermal shutdown and will maintain a high impedance state Space constrained systems in shutdown or when powered off. The driver family also includes hot Security camera networks swap circuitry to protect against false transitions on the bus during Industrial and process control equipment power-up or live insertion.
