DESCRIPTION
The LT®1331 is a 3-driver, 5-receiver RS232 transceiver designed for 3V and mixed 3V/5V systems. Receivers operate from 3V logic supply VL, while the onboard charge pump and drivers operate from 5V or 3V supply VCC.

FEATURES

■ ESD Protection Over ±10kV
■ 120kbaud Operation for RL = 3k, CL = 2500pF
■ 250kbaud Operation for RL = 3k, CL = 1000pF
■ One Low Power Receiver Remains Active While in Shutdown
■ 60µA Supply Current in Shutdown
■ Low Power Driver Disable Mode
■ Uses Small Capacitors: 0.1µF, 0.2µF
■ CMOS Comparable Low Power: 60mW
■ Easy PC Layout: Flowthrough Architecture
■ Rugged Bipolar Design
■ Outputs Assume a High Impedance State When Off or Powered Down

APPLICATIONS
■ Notebook Computers
■ Palmtop Computers
