LTC1348 Datasheet (Linear Technology) - 3.3V/5V Low Power RS232 3-Driver/5-Receiver Transceiver

LTC1348, 3.3V/5V Low Power RS232 3-Driver/5-Receiver Transceiver

DREN: TTL/CMOS Compatible Enable Pin.

Refer to Table 1 for its functional description.

V+: Positive Supply Output (RS232 Drivers).

This pin requires an external capacitor C = 0.1µF for charge storage.

The capacitor may be tied to ground or VCC.

With multiple devices, the V + and V * pins ma
