7 / 15 page ±10kV ESD-Protected, Quad 5V RS-485/RS-422 Transmitters _______________________________________________________________________________________ 7 Detailed Description The MAX3040–MAX3045 are quad RS-485/RS-422 trans- mitters. They operate from a single +5V power supply and are designed to give optimum performance when used with the MAX3093E/MAX3095 5V quad RS-485/ RS-422 receivers or MAX3094E/MAX3096 3V quad RS-485/RS-422 receivers. The MAX3040–MAX3045 only need 1mA of operating supply current and consume 2nA when they enter a low-power shutdown mode. The MAX3040–MAX3045 also feature a hot-swap capability allowing line insertion without erroneous data transfer. The MAX3042B/MAX3045B are capable of transferring data up to 20Mbps, the MAX3041/MAX3044 for data rates up to 2.5Mbps, and the MAX3040/MAX3043 for data rates up to 250kbps. All transmitter outputs are pro- tected to ±10kV using the Human Body Model. ±10kV ESD Protection As with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electro- static discharges (ESD) encountered during handling and assembly. The MAX3040–MAX3045 transmitter outputs have extra protection against electrostatic dis- charges found in normal operation. Maxim’s engineers have developed state-of-the-art structures to protect these pins against the application of ±10kV ESD (Human Body Model), without damage. ESD Test Conditions ESD performance depends on a number of conditions. Contact Maxim for a reliability report that documents test setup, methodology, and results. Human Body Model Figure 6a shows the Human Body Model, and Figure 6b shows the current waveform it generates when dis- charged into low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the device through a 1.5k Ω resistor. R R VOD VOC Y Z Figure 1.
