LTC2802CDE#PBF

LTC2802 is a single and dual RS-232 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. These parts are compatible with the TIA/EIA-232-F standard. Driver outputs are protected from overload and can be shorted to ground or upto ±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. It is used in application such as battery-powered systems, computers and consumer electronics, diagnostic ports etc.

• Maximum data rate is 1Mbps
• Drivers and receivers is 1 + 1
• 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
• VCC supply current is 2.3mA typical at (TA = 25°C, VCC = 1.8V to 5.5V)
• Driver slew rate is 30V/µs max at (VCC = VL = 5.5V, RL = 3KW, CL = 50pF)
• VDD/VEE supply rise time is 0.2ms typical at (TA = 25°C, VCC = 1.8V to 5.5V)
• Operating temperature is 0°C to 70°C
• Package style is 12-lead plastic DFN
