+5V, RS-232 Transceivers
with 0.1µF External Capacitors
General Description
The MAX200–MAX211/MAX213 transceivers are
designed for RS-232 and V.28 communication inter-
faces where ±12V supplies are not available. On-board
charge pumps convert the +5V input to the ±10V need-
ed for RS-232 output levels. The MAX201 and MAX209
operate from +5V and +12V, and contain a +12V to
-12V charge-pump voltage converter.
The MAX200–MAX211/MAX213 drivers and receivers
meet all EIA/TIA-232E and CCITT V.28 specifications at
a data rate of 20kbps. 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.
The 5µW shutdown mode of the MAX200, MAX205,
MAX206, and MAX211 conserves energy in battery-
powered systems. The MAX213 has an active-low shut-
down 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 75µW 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 avail-
able 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.
