LTC2804IGN-1#TRPBF

LTC2804IGN-1#TRPBF is a 1.8V to 5.5V RS-232 single and dual transceiver. It operates 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. This part is 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. Application includes battery-powered systems, computers and consumer electronics, diagnostic ports.
