LTC1386CS#TRPBF Overview

The LTC1386CS#TRPBF is an interface driver, receiver, and transceiver circuit from Linear Technology. The system is a dual-channel, half-duplex, non-inverting, logic-level buffered, serial interface FET switch. The device is housed in a 6-pin SOT223 package, typically used in half duplex applications. It is designed to increase the availability of half-duplex communication by providing an extremely low-power solution that optimizes performance and reliability.

Operating Principle

The LTC1386CS#TRPBF employs a switching logic based on a logic-level input signal. This signal is translated into a buffered logic-level output signal by two internal switches. The switching logic is based on a comparator circuit, triggered when the logic-level signal crosses the detection threshold. When the logic-level signal is high, the internal transistor is enabled, and the output terminal is switched to a high state. When the logic-level input signal crosses the detection threshold and drives the internal comparator in the ‘off’ state, its output signal is toggled to low, and the internal transistor is shutdown.

To ensure reliable data transfer, the device features a signal protection circuit that is triggered by the detection of an over-current event. The signal protection circuit disconnects the output connection to the device and shorts the signal to the ground thereby allowing the signal to persist until the over-current situation is cleared.

Additional features of the LTC1386CS#TRPBF are its variable voltage output, protocol independent switching and low power support. Additionally, the device supports a current-limit stage that can be used to limit the load current effectively, and an inactive (sleep) state to ensure energy efficiency during periods of low activity.

Application Field

The LTC1386CS#TRPBF is an ideal solution for applications requiring an interface between two devices for half-duplex data transfer and access to non-volatile memory. The device is ideal for the following segment of applications:

• Internet of Things (IoT)
