— MAXIM +5V RS-232 Transceivers with 0.1,.F External Capacitors General Description Features 2 The MAX200-MAX211/MAX213 transceivers are designed perior to Bipolar: for RS-232 and V.28 communication interfaces where sav SU pe supplies are not available. On-board charge pumps convert # 0.1p)F to 10yF External Capacitors the +5V input to the #10V needed for RS-232 output levels. 4 20kbits/sec Data Rate bb The MAX201 and MAX209 operate from +5V and +12V, and contain a +12V to -12V charge-pump voltage converter. # 2 Receivers Active in Shutdown Mode (MAX213) The MAX200-MAX211/MAX213 drivers and receivers @ Small 28-Pin SSOP Package - S meet all EIA/TIA-232E and CCITT V.28 specifications at Uses 60% Less Space than SOIC = a data rate of 20kbits/sec. The drivers maintain the +5V . EIA/TIA-232E output signal levels at data rates in * Low-Power Shutdown Current: 1A excess of 120kbits/sec when loaded in accordance —_@ Designed for RS-232 and V.28 Applications with the EIA/TIA-232E specification. ¢ Three-State TTL/CMOS Receiver Outputs The 5yW shutdown mode of the MAX200, MAX205, utp NX MAX206, and MAX211 conserves energy in battery-pow- Orde: rma ered systems. The MAX213 has an active-low shutdown — ring Info tion aa and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing ring indica- tor (RI) to be monitored easily using only 75yW power. MAX200CWP O'Cte x70" 20 Wide SO The MAX211 and MAX213 are available in a 28-pin wide MAX200EPP 740°C to +85°C 20 Plastic DIP small-outline (SO) package, and a 28-pin shrink small- LyaxcqoogWP wae 28S°O 20 wide SO eee SCOT Gee aE a oton 4 area of the SO. The MAX207 is now available in a 24-pin A = SO package and a 24-pin SSOP. The MAX203 and rx) MAX205 use no external components, and are recom- mended for applications with limited circuit board space.
