The MAX200–MAX209/MAX211/MAX213 transceivers
are designed for RS-232 and V.28 communication inter-
faces where Q12V supplies are not available. On-board
charge pumps convert the +5V input to the Q10V needed
for RS-232 output levels. The MAX201 and MAX209
operate from +5V and +12V, respectively, and contain a
+12V to -12V charge-pump voltage converter.
The MAX200–MAX209/MAX211/MAX213 drivers and
receivers meet all EIA/TIA-232E and CCITT V.28 speci-
fications at a 20kbps data rate. The drivers maintain the
Q5V EIA/TIA-232E output signal levels at data rates in
excess of 120kbps when loaded in accordance with the
EIA/TIA-232E specification.
The 5FW shutdown mode of the MAX200, MAX205,
MAX206, and MAX211 conserves energy in battery-pow-
ered systems. The MAX213 has an active-low shutdown
and an active-high receiver enable control. Two receiv-
ers of the MAX213 are active, allowing the ring indicator
(RI) to be monitored easily using only 75FW power.
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 now available in a 24-pin
SO package and a 24-pin SSOP. The MAX203 and
MAX205 use no external components and are recom-
mended for applications with limited circuit board space.
