It uses an internal charge pump to generate +\/-5.5V RS-232 levels from a single supply, requiring only 4 external 0.1uF capacitors. The device meets EIA\/TIA-232-F specifications with 250kbps data rate. \u00b115kV HBM ESD protection on RS-232 pins provides robust ESD protection. The auto-powerdown feature reduces supply current to 1uA when no valid RS-232 signal is detected.","working_principle":"The MAX3232E uses a dual charge pump to generate positive and negative voltage rails from a single 3.0V to 5.5V supply. The first charge pump doubles VCC to approximately +5.5V, and the second inverts this to approximately -5.5V. These rails power the driver output stages, which swing between +5.5V and -5.5V to meet RS-232 specifications. The receivers accept RS-232 levels and convert them to TTL\/CMOS logic levels. The auto-powerdown circuit monitors receiver inputs and enters low-power mode when no valid signal is detected.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>C1+<\/td><td>Cap<\/td><td>Charge pump capacitor 1 positive<\/td><\/tr><tr><td>2<\/td><td>V+<\/td><td>Power<\/td><td>+5.5V generated rail<\/td><\/tr><tr><td>3<\/td><td>C1-<\/td><td>Cap<\/td><td>Charge pump capacitor 1 negative<\/td><\/tr><tr><td>4<\/td><td>C2+<\/td><td>Cap<\/td><td>Charge pump capacitor 2 positive<\/td><\/tr><tr><td>5<\/td><td>C2-<\/td><td>Cap<\/td><td>Charge pump capacitor 2 negative<\/td><\/tr><tr><td>6<\/td><td>V-<\/td><td>Power<\/td><td>-5.5V generated rail<\/td><\/tr><tr><td>7<\/td><td>T2OUT<\/td><td>Output<\/td><td>Driver 2 RS-232 output<\/td><\/tr><tr><td>8<\/td><td>R2IN<\/td><td>Input<\/td><td>Receiver 2 RS-232 input<\/td><\/tr><tr><td>9<\/td><td>R2OUT<\/td><td>Output<\/td><td>Receiver 2 TTL output<\/td><\/tr><tr><td>10<\/td><td>T2IN<\/td><td>Input<\/td><td>Driver 2 TTL input<\/td><\/tr><tr><td>11<\/td><td>T1IN<\/td><td>Input<\/td><td>Driver 1 TTL input<\/td><\/tr><tr><td>12<\/td><td>R1OUT<\/td><td>Output<\/td><td>Receiver 1 TTL output<\/td><\/tr><tr><td>13<\/td><td>R1IN<\/td><td>Input<\/td><td>Receiver 1 RS-232 input<\/td><\/tr><tr><td>14<\/td><td>T1OUT<\/td><td>Output<\/td><td>Driver 1 RS-232 output<\/td><\/tr><tr><td>15<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr><tr><td>16<\/td><td>VCC<\/td><td>Power<\/td><td>Supply voltage (3.0-5.5V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Embedded system debug console UART-to-RS-232<\/li><li>Industrial PLC serial communication port<\/li><li>POS terminal serial printer interface<\/li><li>Medical device programming and data port<\/li><li>Networking equipment management console<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>MAX3232CDR<\/td><td>16-SOIC<\/td><td>Pin-compatible, equivalent<\/td><\/tr><tr><td>ST<\/td><td>ST3232EBDR<\/td><td>16-SOIC<\/td><td>3-5.5V, 250kbps<\/td><\/tr><tr><td>MaxLinear<\/td><td>SP3232EEY-L\/TR<\/td><td>16-TSSOP<\/td><td>3.3V, 250kbps, compatible<\/td><\/tr><tr><td>ADI<\/td><td>MAX3232CSE+T<\/td><td>16-SOIC<\/td><td>1Mbps, higher speed version<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/2638","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=2638"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/2638\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media\/2691"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=2638"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=2638"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=2638"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=2638"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
