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.
