Flowthrough Architecture

The LTC1338 is a 5-driver/ 3-receiver RS232 trans-

ceiver with very low supply current. In the no load

condition, the supply current is only 500

µA. The charge

pump only requires four 0.1

µF capacitors.

In SHUTDOWN mode, the supply current is further

reduced to 0.2

µA. In RECEIVER ALIVE mode, all three

receivers are kept alive and the supply current is 50

µA.

All RS232 outputs assume a high impedance state in

SHUTDOWN and with the power off.

The LTC1338 is fully compliant with all data rate and

overvoltage RS232 specifications. The transceiver can

operate up to 120k baud with a 2500pF, 3k

Ω load. Both

driver outputs and receiver inputs can be forced to

±25V without damage, and can survive multiple ±10kV

ESD strikes.
