MAX202ESE

General Description

The MAX200–MAX209/MAX211/MAX213 transceivers

are designed for RS-232 and V.28 communication interfaces 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 specifications 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-powered systems. The MAX213 has an active-low shutdown

and an active-high receiver enable control. Two receivers 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 smalloutline (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 recommended for applications with limited circuit board space.
