LC709006V-TLM-E-SA

Overview

The LC709006V-TLM-E-SA is a CMOS integrated circuit I/O expander manufactured by Sanyo (now part of ON Semiconductor). It expands microcontroller I/O ports via synchronous serial communication, providing 24-bit parallel I/O. The device supports a wide operating voltage range from 2.0V to 6.0V. Key electrical parameters include an output current capability of 12mA maximum and support for bit-level direction specification, CMOS or N-channel open drain output type selection, and port-level output voltage adjustment.

Feature Summary

• Supports 4-wire or 5-wire synchronous serial transmission and reception interfaces
• Provides 24-bit parallel I/O expansion with configurable output types
• Allows bit-level specification of I/O direction and output drive characteristics
• Enables port-level output voltage adjustment based on peripheral power levels

Applications

• Microcontroller I/O port expansion in embedded systems
• Consumer electronics requiring additional control lines
• Industrial control interfaces with mixed voltage peripherals

Procurement Notes

Verify the manufacturer designation, as Sanyo Semiconductor was acquired by ON Semiconductor. Confirm the specific suffix 'TLM-E-SA' corresponds to the required tape and reel packaging configuration. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the datasheet revision to confirm pinout and electrical specifications match your design intent.

Selection Notes

Select this component when a microcontroller requires expanded parallel I/O capabilities beyond its native pins. It is suitable for applications needing flexible output drive configurations, including open-drain modes. Verify that the system voltage falls within the 2.0V to 6.0V operating range. Consider the synchronous serial interface speed limitations relative to your data throughput requirements.

Part Context

This part belongs to the LC70900x series of I/O expanders designed for microcontroller interfacing. The 'V' variant typically denotes specific voltage or temperature grade variations within the family. The 'TLM-E' suffix indicates surface-mount SSOP packaging, while 'SA' often refers to specific shipping or lot traceability codes defined by the manufacturer.

Replacement Considerations

Direct replacements may include other parts from the LC70900x series with compatible pinouts and electrical characteristics. Verify functional equivalence regarding serial protocol compatibility and output drive strength before substitution.
