31、RIVER/RECEIVERWITH 15-kV ESD PROTECTIONSLLS576EJULY 2021REVISED APRIL 2021Figure 4.Typical Operating Circuit and Capacitor ValuesThe capacitor type used for C1C4is not critical for proper operation.The MAX202requires 0.1-F capacitors,although capacitors up to 10F can be used without harm.Ceramic die
32、lectrics are suggested for the 0.1-F capacitors.When using the minimum recommended capacitor values,make sure the capacitance value does not degrade excessively as the operating temperature varies.If in doubt,use capacitors with a larger (e.g.,2)nominal value.The capacitorseffective series resistanc
33、e (ESR),which usually rises at low temperatures,influences the amount of ripple on V+and V.Use larger capacitors (up to 10F)to reduce the output impedance at V+and V.Bypass V CC to ground with at least 0.1F.In applications sensitive to power-supply noise generated by the charge pumps,decouple V CC t
34、o ground with a capacitor the same size as (or larger than)the charge-pump capacitors (C1C4).TI MAX202devices have standard ESD protection structures incorporated on the pins to protect against electrostatic discharges encountered during assembly and handling.In addition,the RS232bus pins (driver ou
35、tputs and receiver inputs)of these devices have an extra level of ESD protection.Advanced ESD structures were designed to successfully protect these bus pins against ESD discharge of 15-kV when powered down.http:/ Test ConditionsHuman-Body Model (HBM)R VHBM1001502005001.51.00.50.0I -AD U T Machine M
