Description

The LTC2801/LTC2802/LTC2803/LTC2804 are single and dual RS-232 transceivers in narrow SSOP and chip-scale DFN packages. All operate over a supply range of 1.8V to 5.5V, which permits operation directly from two alkaline, NiCd or NiMH cells. An integrated DC-to-DC converter generates power supplies for driving RS-232 levels. A logic supply pin allows easy interfacing with different logic levels independent of the DC-DC supply.These parts are compatible with the TIA/EIA-232-F standard. Driver outputs are protected from overload and can be shorted to ground or up to ±15V without damage. To extend battery life, receivers can be kept active, operating at reduced speed, with only 15μA current. In shutdown mode, current is further reduced to 1μA.Part NumberDriver & ReceiversMax Data RateModesPackageLTC28011 + 10.25MbpsSD, RA, DD, AODFN-12LTC28021 + 11MbpsSD, RA, DD, AODFN - 12LTC28032 + 20.25MbpsSD, RA, DD, AODFN-16LTC2803-12 + 20.25MbpsSD, AOSSOP-16LTC28042 + 21MbpsSD, RA, DD, AODFN-16LTC2804-12 + 21MbpsSD, AOSSOP-16ApplicationsBattery-Powered SystemsComputers and Consumer ElectronicsDiagnostic Ports
