LTC2803CDHC#PBF

LTC®2803 is single RS-232 transceiver. 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 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.

• 2 driver and 2 receiver
• 0.25Mbps maximum data rate
• 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
• Package style is 16-lead plastic DFN
• Temperature range from 0°C to 70°C
