XR33193/XR33194/XR33195
3.3V, 20Mbps, TSOT23 RS-485/RS-422
Transmitters with ±15kV ESD Protection
Description
The XR33193, XR33194, and XR33195 are a high performance
RS-485/RS-422 driver family offered in a tiny TSOT23 package
designed to meet the increasing system requirements found in today’s
performance serial communication applications. These standalone
drivers operate off a single 3.3V supply and meet RS-485 and RS-422
standards for balanced RS-485 and RS-422 serial communications
networks.
The driver family offers several speed options to maximize performance
in different applications. The XR33193 and XR33194 have slew limited
outputs for reduced EMI and for error free communication over long
or improper/unterminated data cables or multi-drop applications with
unterminated stubs. The XR33195 driver operates at data rates up to
20Mbps with tight skew and prop delay spec’s required by demanding
high speed applications. All parts in the XR33193/94/95 driver family
operate over the extended temperature range of -40°C to 125°C.
The XR33193/94/95 driver family is protected by short-circuit detection
as well as thermal shutdown and will maintain a high impedance state
in shutdown or when powered off. The driver family also includes hot
swap circuitry to protect against false transitions on the bus during
power-up or live insertion.
For companion standalone RS-485/RS-422 receivers in tiny TSOT23
packages see our XR33180/81/83/84 product datasheet.
