________________General Description
The MAX212 RS-232 transceiver is intended for 3V-pow-
ered EIA/TIA-232E and V.28/V.24 communication inter-
faces where 3 drivers and 5 receivers are needed with
minimum power consumption. The operating voltage
range extends from 3.6V down to 3.0V while still main-
taining true RS-232 and EIA/TIA-562 voltage levels.
A 1碌A typical shutdown mode reduces power con-
sumption, extending 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 CMOS MAX212 to be in low-power
shutdown mode and monitor incoming RS-232 activity.
A guaranteed data rate of 120kbps provides compati-
bility with popular software for communicating with per-
sonal computers.
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.
The MAX212 is available in both small-outline (SO) and
shrink-small-outline (SSOP) packages. The SSOP
package occupies less than half of the board area
required by the equivalent SO package.
