LTC1471CS#PBF

Overview

The LTC1471CS#PBF is a power switch IC designed for PCMCIA applications, featuring integrated protection for 3.3V and 5V VCC lines. It utilizes a 16-lead SOIC package with a narrow 0.15-inch width. The device supports a 2:1 input-to-output ratio and operates within a commercial temperature range of 0°C to +70°C. It is manufactured by Analog Devices Inc. and belongs to the LTC1471 series.

Feature Summary

• Integrated protection for dual voltage rails
• PCMCIA compliant switching architecture
• N-channel power switch configuration

Applications

• PCMCIA card slot power management
• 3.3V system bus switching
• 5V system bus switching

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status via official datasheets. Ensure the specific suffix matches required packaging formats. Cross-reference ordering information with current manufacturer availability lists to avoid obsolete stock.

Selection Notes

Select this component for designs requiring protected switching in legacy PCMCIA interfaces. Evaluate thermal performance within the specified 0°C to +70°C operating range. Consider the 16-lead SOIC footprint for PCB layout constraints. Verify compatibility with target system voltage levels before integration.

Part Context

This part belongs to the LTC1471 family of power distribution switches. It is distinct from other Analog Devices ADCs or regulators like the LTC2171 or LTC1474. The CS#PBF designation indicates a commercial temperature grade and tube packaging format.

Replacement Considerations

Consult official Analog Devices documentation for direct pin-compatible substitutes. Verify functional equivalence for PCMCIA protection requirements before substitution.
