Interface
n Logic Supply Pin for Easy Level-Shifting to UART or
Microprocessor
n Low-Latency Output Enable Allows Line Sharing and
Half-Duplex Operatio True RS-232 Compliant Output Levels
n Small Footprint: LTC2801/LTC2802 4mm Г— 3mm DFN Package LTC2803/LTC2804 Narrow SSOP-16 and 5mm Г— 3mm DFN Packages The LTCВ®2801/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. LTC2801 1+1 Applications LTC2802 1+1 n Battery-Powered Systems
