Overview
The LTC1470CS8#TRPBF is a power distribution switch IC manufactured by Analog Devices Inc. It features two independent N-channel switches with 2:1 multiplexing capability, housed in an 8-SOIC package. The device supports input voltages of 3.3V and 5V, delivering up to 1A output current per channel. Designed for PCMCIA applications, it provides protected switching functionality within the SO-8 (0.154 inch width) footprint.
Feature Summary
- Integrates dual N-channel power switches with 2:1 multiplexing control
- Provides protected switching for 3.3V and 5V PCMCIA bus lines
- Delivers 1A continuous output current capability per channel
Applications
- PCMCIA card protection circuits
- Power distribution systems requiring redundant switching
- Bus isolation and protection interfaces
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the 8-SOIC package dimensions match your PCB layout requirements. Ensure the 1A current rating aligns with your load specifications. Check for RoHS compliance status through official manufacturer documentation before finalizing procurement decisions.
Selection Notes
Select this component when designing PCMCIA-compatible systems requiring dual-channel protection. The 2:1 multiplexing feature allows seamless switching between primary and backup power sources. Consider the 8-SOIC package size for space-constrained designs. Verify thermal performance under maximum load conditions to ensure reliable operation within specified temperature ranges.
Part Context
This part belongs to Analog Devices' power switch IC family designed for portable electronics. It complements other LTC14xx series components offering various protection levels. The CS8 designation indicates commercial temperature range operation in an SOIC-8 package. This series addresses the growing demand for compact, integrated power management solutions in mobile devices.
Replacement Considerations
LTC1470CS8#PBF is available in tube packaging as an alternative to the TRPBF reel version. Both variants share identical electrical characteristics and pin configurations. Verify packaging preferences based on assembly line requirements. No functional differences exist between the suffix variations.
