LTC1384IN#PBF

Drivers, Receivers, Transceivers Overview

The LTC1384IN#PBF is an ultra-low power RS-232 transceiver manufactured by Analog Devices Inc., featuring two drivers and two receivers. It operates from a single 5V supply with a quiescent current of 220µA in Normal mode and drops to 35µA in Shutdown mode while keeping both receivers active. The device supports data rates up to 120kBaud and utilizes four 0.1µF capacitors for its charge pump. It provides ±10kV ESD protection on I/O lines and withstands ±25V overvoltage without damage. The component is housed in an 18-lead SOIC package and is rated for an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power consumption with dedicated shutdown mode that maintains receiver functionality
• Robust input/output protection against electrostatic discharge and high voltage overloads
• Minimal external component requirement using small 0.1µF capacitors for charge pumping
• TTL/CMOS compatible logic inputs and outputs with integrated pull-up resistors

Drivers, Receivers, Transceivers Applications

• Notebook computers requiring low standby power
• Palmtop computers and handheld devices
• Battery-powered serial communication systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix IN#PBF corresponds to the industrial temperature grade (-40°C to +85°C) and the 18-lead plastic SOIC package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as suffix variations may impact environmental certifications and material composition requirements for your assembly process.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require full-duplex RS-232 communication with minimal power draw during idle periods. Ensure the application environment stays within the specified -40°C to +85°C temperature range. Verify that the available board space accommodates the required four 0.1µF capacitors for the charge pump circuit. Consider the 18-lead SOIC footprint constraints during PCB layout planning.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1384 family of 5V low-power RS-232 transceivers. It shares functional similarities with the LTC1382 and LTC1383 but differs in package options and specific pin configurations. The IN suffix denotes the industrial temperature variant, distinct from the commercial C version. It serves as a direct replacement for legacy parts like the LT1180A in many designs due to pin compatibility.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states the device is pin-compatible with the LT1180A. Designers replacing other components should verify that the substitute matches the 18-lead SOIC package dimensions and electrical characteristics, particularly the shutdown current specifications and ESD protection levels.
