1384

The LTC1384 is an ultra-low power RS232 transceiver designed for single 5V supply operation. It integrates two drivers and two receivers, making it suitable for various communication interfaces. The device consumes only 220µA in normal mode and can reduce consumption to 35µA in shutdown mode, with receivers remaining active.

This transceiver supports data rates up to 120kBaud with a 2500pF, 3kΩ load. It offers robust protection, including ±10kV ESD strikes and the ability for driver outputs and receiver inputs to withstand ±25V without damage. The charge pump requires only four 0.1µF capacitors, simplifying board design.

The LTC1384 is pin-compatible with the LT1180A and is well-suited for applications in notebook and palmtop computers where low power consumption and space-saving are critical. The receiver outputs can be forced into a three-state condition using the receiver enable (RX EN) pin.

Key electrical specifications include a typical supply current of 220µA in normal operation and 35µA in shutdown mode. The operating temperature range for the LTC1384C variant is 0°C to 70°C. The device utilizes small 0.1µF capacitors for its charge pump.
