The MAX212 RS-232 transceiver is intended for 3V-powered EIA/TIA-232E and V.28/V.24 communication interfaces where three drivers and five receivers are needed with minimum power consumption. The operating voltage range extends from 3.6V down to 3.0V while still maintaining true RS-232 and EIA/TIA-562 voltage levels.
A 1µA typical shutdown mode reduces power consumption, 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 compatibility with popular software for communicating with personal computers.
Three-state drivers on all receiver outputs are provided so that multiple receivers, generally of different interface 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.
