XR33194中文资料3.3V, 2.5Mbps, TSOT23 RS-485/RS-422 Transmitter with ±15kV ESD Protection数据手册MaxLinear规格书

描述 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.
