Product Summary

The ADM222, ADM232A, ADM242 are a family of high speedRS-232 line drivers/receivers offering transmission rates up to200 kB/s. Operating from a single +5 V power supply, a highlyefficient on-chip charge pump using small (0.1μF) externalcapacitors allows RS-232 bipolar levels to be developed. TwoRS-232 drivers and two RS-232 receivers are provided on eachdevice.
