Working Principles

The ADM238LARZ is a single-chip RS-232 line driver/receiver. It operates by converting TTL/CMOS logic levels to RS-232 voltage levels and vice versa. The DE (Driver Enable) and RE (Receiver Enable) pins control the direction of data transmission. When DE is high and RE is low, the device operates in transmit mode, converting TTL/CMOS signals to RS-232 levels on the RO pin. When DE is low and RE is high, the device operates in receive mode, converting RS-232 signals to TTL/CMOS levels on the RI pin.

Detailed Application Field Plans

The ADM238LARZ is commonly used in various communication and data transmission applications, including:

  1. Personal Computers
  2. Modems
