LC709006A-TLM-E

Overview

The LC709006A-TLM-E is a CMOS I/O expander designed to extend microcontroller capabilities via synchronous serial communication. It provides 24-bit parallel I/O with configurable direction, output type (CMOS or N-channel open drain), and voltage levels per port. Operating within a wide supply range of 2.0V to 6.0V, it supports 4-/5-wire synchronous transmission. The device features a maximum output current of 12mA and allows bit-level specification for I/O direction and output type, enabling flexible integration in diverse electronic systems.

Feature Summary

• Supports 4- or 5-wire synchronous serial communication interfaces for data transmission and reception.
• Provides 24-bit parallel I/O expansion with independent bit-level control over input/output direction.
• Allows configurable output types including standard CMOS and N-channel open drain modes at the bit level.
• Enables port-based output voltage adjustment to match peripheral equipment power requirements.

Applications

• Microcontroller I/O port expansion in embedded systems
• Peripheral interface management requiring voltage level adaptation
• General-purpose digital input/output expansion in consumer electronics

Procurement Notes

Verify the specific suffix -TLM-E against official onsemi documentation to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with system voltage ranges and serial interface protocols before procurement. Cross-reference ordering numbers with manufacturer datasheets to avoid substitution errors.

Selection Notes

Select this component when expanding MCU I/O ports via synchronous serial interfaces is required. Consider the 2.0V to 6.0V operating range and 12mA output drive capability. Evaluate the need for configurable output types and voltage levels. Verify package availability and thermal performance for the target application environment.
