What are the key features of LT1039ISW#PBF?
- Triple RS-232 driver with Schmitt-trigger inputs for noise-immune serial communication in industrial environments
- Active receiver under shutdown mode allows bus monitoring without full-power operation, reducing system power consumption
- 18-pin SOIC package simplifies board layout for multi-channel EIA-232 interface designs
What is LT1039ISW#PBF used for?
LT1039ISW#PBF is designed for multi-channel RS-232 serial communication in embedded systems, industrial controllers, and telecommunications equipment. Its 3-driver configuration supports simultaneous connection to multiple serial peripherals from a single IC, while the Schmitt-trigger inputs reject noise on long cable runs. The active-under-shutdown receiver makes it particularly useful in systems that require wake-on-serial-data functionality without full-chip power consumption.

Frequently Asked Questions
How many RS-232 driver channels does LT1039ISW#PBF provide, and what input type does it use?
LT1039ISW#PBF integrates 3 RS-232 driver channels with Schmitt-trigger inputs, providing hysteresis to reject noise on long cable runs typically exceeding 1 meter in industrial environments where signal integrity is a concern.
Can LT1039ISW#PBF maintain serial bus monitoring during low-power shutdown mode?
Yes, LT1039ISW#PBF keeps 1 receiver active during shutdown mode, allowing the host processor to monitor incoming RS-232 data at EIA-232 voltage levels (±15 V maximum) without powering up the full 3-driver array, reducing system quiescent current.
What package and pin count does LT1039ISW#PBF come in, and how does this affect PCB layout for triple-channel RS-232 designs?
LT1039ISW#PBF uses an 18-pin SOIC package, which provides enough pins to route all 3 driver outputs and receiver inputs while maintaining the standard 1.27 mm pitch of SOIC, simplifying PCB routing compared to smaller packages in multi-channel RS-232 interface designs.
In what scenarios would LT1039ISW#PBF be preferred over a single-channel RS-232 transceiver?
LT1039ISW#PBF is preferred when a design requires 3 simultaneous RS-232 channels from a single IC, reducing BOM count and board space compared to using three separate single-channel transceivers, each occupying approximately 8 pins and additional decoupling capacitors at EIA-232 ±15 V signal levels.
