Overview

  • 1.8V to 5.5V Supply Voltage
  • Single and Dual Transceivers
  • High-Speed Operation
    • 1Mbps for 250pF/3kΩ Load (LTC2802, LTC2804)
    • 250kbps for 1nF/3kΩ Load
    • 100kbps for 2.5nF/3kΩ TIA/EIA-232-F Load
  • Low-Power 1μA Shutdown and 15μA Receivers-Active Modes
  • No Damage or Latchup 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
  • Small Footprint:
    • LTC2801/LTC2802 4mm × 3mm DFN Package
    • LTC2803/LTC2804 Narrow SSOP-16
    • 5mm × 3mm DFN Packages

The LTC2801/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.

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.
