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 stan-
dard. 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 15A current. In shutdown
mode, current is further reduced to 1A.
