1.8V to 5.5V RS-232
Single and Dual Transceivers
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 15μA current. In shutdown
mode, current is further reduced to 1μA. Line sharing and
half-duplex operation are also supported.
