EVALUATION KIT AVAILABLE

General Description

The MAX202E-MAX213E, MAX232E, and MAX241E are a

family of RS-232 and V.28 transceivers with high ±15kV

ESD HBM protection and integrated charge pump circuit-

ry for single +5V supply operation. The various combina-

tions of features are outlined in the

Selector Guide.

The

drivers and receivers for all ten devices meet all EIA/TIA-

232E and CCITT V.28 specifications at data rates up to

120kbps when loaded.

The MAX211E/MAX213E/MAX241E are available in 28-

pin SO and SSOP packages. The MAX202E/MAX232E

come in 16-pin TSSOP, narrow SO, wide SO, and DIP

packages. The MAX203E comes in a 20-pin DIP/SO

package, and needs no external charge-pump capaci-

tors. The MAX205E comes in a 24-pin wide DIP pack-

age, and also eliminates external charge-pump

capacitors.

The MAX213E’s receiver propagation delay is typically 0.5µs in normal operation. In shutdown mode, propagation delay increases to 4µs for both rising and falling transitions. The MAX213E’s receiver inputs have approximately 0.5V hysteresis, except in shutdown, when receivers R4 and R5 have no hysteresis.
