The LTC2804CGN-1#PBF is a single and dual RS-232 Transceiver operates over a supply range of 1.8 to 5.5V, which permits operation directly from two alkaline, NiCd or NiMH cells. An integrated DC/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 and both receiver and driver outputs assume a high impedance state.

• Single and dual transceiver
• High-speed operation
• 1Mbps for 250pF/3kR load
• 250kbps for 1nF/3kR load
• 100kbps for 2.5nF/3kR TIA/EIA-232-F load
• Low-power 1μA shutdown and 15μA receivers active modes
• No damage or latch-up to ±10kV ESD on RS-232 interface
• Logic supply pin for easy level-shifting to UART or microprocessor
• Low-latency output enable allows line sharing and half-duplex operation
• True RS-232 compliant output levels
