General Description
The MAX13234E–MAX13237E are +3V to +5.5V pow-
ered EIA/TIA-232 and V.28/V.24 communications inter-
faces with high data-rate capabilities (up to 3Mbps), a
flexible logic voltage interface, and enhanced electro-
static discharge (ESD) protection. All receiver inputs
and transmitter outputs are protected to ±15kV IEC
61000–4-2 Air Gap Discharge, ±8kV IEC 61000-4-2
Contact Discharge, and ±15kV Human Body Model.
The MAX13234E/MAX13235E have two receivers and
two transmitters, while the MAX13236E/MAX13237E
have a single receiver and transmitter. The transmitters
have a low-dropout transmitter output stage, delivering
true RS-232 performance from a +3V to +5.5V supply
based on a dual charge pump. The charge pump
requires only four small 0.1F capacitors for operation
from a +3.3V supply.
All devices achieve a 1A supply current using Maxim’s
AutoShutdown Plus feature. These devices automati-
cally enter a low-power shutdown mode when the
RS-232 cable is disconnected or the devices driving
the transmitter and receiver inputs are inactive for more
than 30s.
The MAX13234E–MAX13237E are available in space-
saving TQFN and TSSOP packages and operate over
the -40°C to +85°C extended temperature range.
