General Description
The MAX221E is a +5V powered, single transmit/
receive RS-232 and V.28 communications interface with
automatic shutdown/wake-up features and high data
rate capabilities.
The MAX221E features enhanced electrostatic discharge
(ESD) protection. Both the transmitter output and receiver
input are protected to ±15kV using the IEC 1000-4-2 Air-
Gap Discharge Method, to ±8kV using the IEC 1000-4-2
Contact Discharge Method, and to ±15kV using the
Human Body Model.
The MAX221E achieves a low 1μA supply current with
Maxim’s revolutionary AutoShutdown feature.
AutoShutdown saves power without changes to the
existing BIOS or operating system by entering low-
power shutdown mode when the RS-232 cable is dis-
connected or when the transmitter of the connected
peripheral is off. The MAX221E wakes up and drives the
INVALID
pin high when an active RS-232 cable is con-
nected, signaling the host that a peripheral is connected
to the communications port.
The MAX221E is available in a 16-pin SSOP package as
well as a 16-pin TSSOP that uses 50% less board space
than a 16-pin SO.
