It meets TIA\/EIA-232-F and ITU V.28 standards, providing the electrical interface between asynchronous communication controllers and serial-port connectors. The charge pump and four 0.1 \u00b5F external capacitors enable operation from a single 3.0V to 5.5V supply. The device supports data rates up to 250 kbps with a maximum driver output slew rate of 30 V\/\u00b5s. It accepts 5V logic inputs with a 3.3V supply and features fail-safe receiver outputs that go high when inputs are open.","working_principle":"The MAX3232ESE+ uses an internal dual charge pump to generate the positive and negative supply voltages required for RS-232 signal levels from a single 3.0-5.5V supply. The first charge pump doubles VCC to create V+ (approximately +5.5V), and the second inverts V+ to create V- (approximately -5.5V). These generated voltages power the driver outputs, which swing between +5.5V and -5.5V to meet the RS-232 specification of \u00b13V minimum with 5 kOhm load. The receivers convert RS-232 input levels (\u00b13V to \u00b115V) to TTL\/CMOS output levels. A 5 kOhm pulldown resistor on each receiver input ensures the output goes high when the input is open (fail-safe). The ESD protection structures on RS-232 pins use SCR-based clamping to absorb transient energy up to \u00b115 kV per IEC 61000-4-2 without latchup.","pin_description":"<table border=\"1\" cellpadding=\"4\">\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Description<\/th><\/tr>\n<tr><td>1<\/td><td>C1+<\/td><td>Passive<\/td><td>Positive terminal of voltage doubler capacitor<\/td><\/tr>\n<tr><td>2<\/td><td>V+<\/td><td>Power<\/td><td>+5.5V output from charge pump<\/td><\/tr>\n<tr><td>3<\/td><td>C1-<\/td><td>Passive<\/td><td>Negative terminal of voltage doubler capacitor<\/td><\/tr>\n<tr><td>4<\/td><td>C2+<\/td><td>Passive<\/td><td>Positive terminal of inverting capacitor<\/td><\/tr>\n<tr><td>5<\/td><td>C2-<\/td><td>Passive<\/td><td>Negative terminal of inverting capacitor<\/td><\/tr>\n<tr><td>6<\/td><td>V-<\/td><td>Power<\/td><td>-5.5V output from charge pump<\/td><\/tr>\n<tr><td>7<\/td><td>DOUT2<\/td><td>Output<\/td><td>RS-232 driver 2 output<\/td><\/tr>\n<tr><td>8<\/td><td>RIN2<\/td><td>Input<\/td><td>RS-232 receiver 2 input<\/td><\/tr>\n<tr><td>9<\/td><td>ROUT2<\/td><td>Output<\/td><td>TTL\/CMOS receiver 2 output<\/td><\/tr>\n<tr><td>10<\/td><td>DIN2<\/td><td>Input<\/td><td>TTL\/CMOS driver 2 input<\/td><\/tr>\n<tr><td>11<\/td><td>DIN1<\/td><td>Input<\/td><td>TTL\/CMOS driver 1 input<\/td><\/tr>\n<tr><td>12<\/td><td>ROUT1<\/td><td>Output<\/td><td>TTL\/CMOS receiver 1 output<\/td><\/tr>\n<tr><td>13<\/td><td>RIN1<\/td><td>Input<\/td><td>RS-232 receiver 1 input<\/td><\/tr>\n<tr><td>14<\/td><td>DOUT1<\/td><td>Output<\/td><td>RS-232 driver 1 output<\/td><\/tr>\n<tr><td>15<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr>\n<tr><td>16<\/td><td>VCC<\/td><td>Power<\/td><td>Supply voltage (3.0V to 5.5V)<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li><strong>Embedded RS-232:<\/strong> Industry-standard dual transceiver adds serial ports to any 3.3V or 5V microcontroller system<\/li>\n<li><strong>Industrial PCs:<\/strong> \u00b115 kV ESD protection withstands electrostatic discharge from frequently connected serial cables<\/li>\n<li><strong>Battery-Powered Devices:<\/strong> 300 \u00b5A supply current and charge pump operation from 3.0V minimize battery drain<\/li>\n<li><strong>Legacy Interface:<\/strong> Converts modern 3.3V logic to RS-232 levels for communication with older equipment and test instruments<\/li>\n<li><strong>Data Center Equipment:<\/strong> Reliable serial management interface with IEC ESD protection for server and networking equipment<\/li>\n<\/ul>","alternative_models":"<table border=\"1\" cellpadding=\"4\">\n<tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr>\n<tr><td>MAX3232CSE+<\/td><td>ADI<\/td><td>Commercial temp (0-70\u00b0C), lower ESD rating<\/td><\/tr>\n<tr><td>SP3232EEN-L\/TR<\/td><td>MaxLinear<\/td><td>Pin-compatible, 3.0-5.5V, 250kbps<\/td><\/tr>\n<tr><td>ST3232EBDR<\/td><td>ST<\/td><td>3.0-5.5V, 400kbps, SOIC-16<\/td><\/tr>\n<tr><td>SN65C3232EDWR<\/td><td>TI<\/td><td>1 Mbps, extended temp, pin-compatible<\/td><\/tr>\n<tr><td>MAX3222ESE+<\/td><td>ADI<\/td><td>With shutdown and auto-powerdown (1 \u00b5A)<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7809","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=7809"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7809\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=7809"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=7809"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=7809"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=7809"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
