MAX200–MAX209/  
MAX211/MAX213  
+5V, RS-232 Transceivers  
with 0.1μF External Capacitors  
General Description  
MAX200-MAX209, MAX211, and MAX213 are a family  
of RS-232 and V.28 transceivers with integrated charge  
pump circuitry for single +5V supply operation.  
Applications  
Battery-Powered Equipment  
Handheld Equipment  
Portable Diagnostics Equipment  
The drivers maintain the ±5V EIA/TIA-232E output signal  
levels at data rates in excess of 120kbps when loaded in  
accordance with the EIA/TIA-232E specification.  
Typical Operating Circuit  
+5V INPUT  
The MAX211 and MAX213 are available in a 28-pin, wide  
small-outline (SO) package and a 28-pin shrink small-  
outline (SSOP) package, which occupies only 40% of the  
area of the SO. The MAX207 is available in a 24-pin SO  
package and a 24-pin SSOP. The MAX203 and MAX205  
use no external components and are recommended for  
applications with limited circuit board space.
