LTC1384CG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1384CG#TRPBF is a low-power RS-232 transceiver manufactured by Analog Devices Inc. It features two drivers and two receivers, operating from a single 5V supply with a typical quiescent current of 220µA in Normal mode. In Shutdown mode, the supply current drops to 35µA while keeping both receivers active. The device supports data rates up to 120kBaud and utilizes four 0.1µF capacitors for its charge pump. It operates within a commercial temperature range of 0°C to 70°C and is housed in a 20-lead SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power consumption with 220µA quiescent current and 35µA shutdown current
• Dual receiver functionality maintained during shutdown mode
• Robust protection against ±10kV ESD strikes on I/O lines
• Compatible with TTL/CMOS logic inputs

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the CG suffix corresponds to the commercial temperature range (0°C to 70°C) required for the intended application environment. Ensure compatibility with standard surface-mount assembly processes for the 20-lead SSOP package.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring minimal power consumption in battery-operated devices where continuous receiver monitoring is necessary. The 20-lead SSOP package offers a compact footprint suitable for space-constrained designs. Consider the 120kBaud maximum data rate and the requirement for external 0.1µF capacitors when designing the circuit layout.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1384 family of ultra-low power RS-232 transceivers. It is pin-compatible with the LT1180A, facilitating direct upgrades or replacements in existing designs. The family includes variants with different package options and temperature ranges, such as the industrial grade LTC1384I.

Drivers, Receivers, Transceivers Replacement Considerations

The LT1180A is a pin-compatible alternative. Other family members like the LTC1382 offer similar electrical characteristics but may differ in package availability or specific thermal performance metrics.
