Shutdown Control. Connect to VCC
for normal operation. Connect to
GND to shut down the power supply
and to disable the drivers. Receiver
status is not changed by this control.
Receiver Enable Control. Connect
to VCC for normal operation.
Connect to GND to force the

_______________Detailed Description
The MAX212 line driver/receiver is intended for 3V-
powered EIA/TIA-232E and V.28/V.24 communications
interfaces where 3 drivers and 5 receivers are
required. The operating voltage range extends from
3.6V down to 3.0V while still maintaining true RS-232
and EIA/TIA-562 transmitter output voltage levels.
The circuit comprises three sections: power supply,
transmitters, and receivers. The power-supply sec-
tion converts the supplied 3V to about ±6.5V, to pro-
vide the voltages necessary for the drivers to meet
true RS-232 levels. External components are small
and inexpensive.
The transmitters and receivers are guaranteed to oper-
ate at data rates of 120kbps.
A shutdown mode reduces current to 1A to extend
battery life in portable systems. While shut down, all
receivers can remain active or can be disabled under
logic control. This enables a system incorporating the
MAX212 to be in low-power shutdown mode and still
monitor incoming RS-232 activity.
Three-state drivers on all receiver outputs are provided
so that multiple receivers, generally of different inter-
face standards, can be wire-ORed at the UART.
