9 / 25 page ![]() +3V to +5V, 2500VRMS Isolated RS-485/RS-422 Transceivers with ±15kV ESD Protection _______________________________________________________________________________________ 9 SWITCHING ELECTRICAL CHARACTERISTICS (MXL1535E) (VCC1 = +4.5V to +5.5V, VCC2 = +4.5V to +7.5V, RL = 27 Ω, CL = 50pF, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC1 = +5V, VCC2 = +5V, TA = +25°C.) PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS Data Sample Jitter tJ Figure 6 220 285 ns Max Baud Rate fMAX SLO = high, Figure 5, (Note 6) 250 450 kBd SLO = high, Figures 2, 6 430 855 Driver-Differential Output Delay Time tDD SLO = low, Figures 2, 6 850 1560 ns SLO = high, VCC2 = +4.5V 45 100 Driver-Differential Output Transition Time tTD SLO = low, VCC2 = +4.5V 150 260 1000 ns Driver-Output Enable Time tPZL, tPZH SLO = high, DI = high or low, Figure 3, 7 730 1400 ns Driver-Output Disable Time tPHZ, tPLZ SLO = high, DI = high or low, Figures 3, 7 720 1300 ns Receiver-Propagation Delay Time to RO1 tPLH1, tPHL1 Figures 4, 8 440 855 ns Receiver-Propagation Delay Time to RO2 tPLH2, tPHL2 Figures 4, 8 40 ns RO1, RO2 Rise or Fall Time tR, tF Figures 4, 8 40 ns Receiver-Output Enable Time RO1 tZL, tZH Figures 4, 9 30 ns Receiver-Output Disable Time RO1 tLZ,tHZ Figures 4, 9 30 ns Initial Startup Time (from Internal Communication Fault) (Note 5) 1200 ns Internal Communication Timeout Fault Time (Note 5) 1200 ns 0°C to +70°C 56 ST1, ST2 Duty Cycle -40°C to +85°C 57 % ESD Protection Human Body Model (A, B, Y, Z) ±15 kV Note 1: Receiver inputs are 96k Ω minimum resistance, which is 1/8 unit load. Note 2: 60s test result is guaranteed by correlation from 1s result. Note 3: VISO is the voltage difference between GND1 and GND2. Note 4: The maximum data rate is specified using the maximum jitter value according to the formula: data rate = 1 / (4tJ). See the Skew section for more information. Note 5: Initial startup time is the time for communication to recover after a fault condition. Internal communication timeout fault time is the time before a fault is indicated on RE,after internal communication has stopped. Note 6: Bd = 2 bits. |
