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.
