LTC1383CS#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1383CS#TRPBF is a low-power RS232 transceiver manufactured by Analog Devices Inc. It operates from a single 5V supply and features two drivers and two receivers. The device draws a typical quiescent supply current of 220µA with unloaded outputs. It supports data rates up to 120kBaud with a 2500pF, 3kΩ load. The charge pump requires four 0.1µF capacitors. Driver propagation delay is typically 2µs, while receiver propagation delay is typically 0.3µs. The component is housed in a 16-lead plastic SOIC narrow package.

Drivers, Receivers, Transceivers Feature Summary

• Operates from a single 5V supply using only four small 0.1µF capacitors for the charge pump
• Provides ESD protection exceeding ±10kV on both driver outputs and receiver inputs
• Features output overvoltage protection that prevents current backflow into supplies when I/O lines are forced to ±25V

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging rather than tube packaging. Confirm the CS suffix corresponds to the commercial temperature range of 0°C to 70°C. Ensure the datasheet version matches the required electrical specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring ultra-low power consumption from a single 5V source. It serves as a pin-compatible replacement for LT1181A and MAX232A devices. Consider the 220µA supply current and 120kBaud maximum data rate when designing serial communication interfaces for portable electronics.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1383 family of 5V low power RS232 transceivers. It shares functional similarities with the LTC1382 and LTC1384 but lacks shutdown modes found in other variants. The CS designation identifies the specific package style and operating temperature range within the broader product line.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly lists the LT1181A and MAX232A as pin-compatible alternatives. Verify voltage levels and ESD ratings against these specific models if cross-referencing for design substitution purposes.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate supported by the LTC1383?

The transceiver can operate up to 120kBaud with a 2500pF, 3kΩ load.

How does the device handle overvoltage on the RS232 lines?

Both driver outputs and receiver inputs can be forced to ±25V without damage, and the output overvoltage does not force current back into the supplies.

What is the typical quiescent supply current?

The supply current (ICC) is 220µA with driver outputs unloaded at 25°C.
