JLC1562BFEL

Overview

The JLC1562BFEL is an I2C Bus I/O expander manufactured by onsemi, packaged in a SOEIAJ-16 (CASE 966) format. It provides an 8-bit bidirectional input/output port and a 6-bit resolution Digital to Analog Converter (DAC). The device operates within a DC supply voltage range of 4.2 V to 6.0 V and supports an operating temperature range from -40°C to +85°C. It features a selectable 3-bit address via pins A0-A2, allowing up to eight devices on the same bus. The SCL clock frequency is limited to a maximum of 100 kHz.

Feature Summary

• Supports I2C Bus protocol with selectable 3-bit hardware addressing for multi-device configurations.
• Integrates a 6-bit DAC output and five comparators for analog threshold monitoring.
• Features open-drain I/O outputs with internal pull-up resistors on address inputs.
• Includes power-down mode protection against external bus currents.

Applications

• I2C Bus expandibility in embedded systems requiring additional GPIO ports.
• Analog signal monitoring using integrated comparators and DAC outputs.
• Low-power industrial control interfaces operating within specified voltage ranges.

Procurement Notes

Verify the specific ordering suffix BFEL corresponds to the SOEIAJ-16 package configuration. Confirm that the component meets RoHS compliance requirements if lead-free status is necessary for the assembly process. Ensure the procurement documentation matches the manufacturer's specifications for the JLC1562B series to guarantee functional compatibility.

Selection Notes

Select this component when an I2C interface is required to expand digital I/O capabilities alongside analog functions. The 6-bit DAC and comparator features are suitable for applications needing simple analog-to-digital conversion or threshold detection without external components. Verify that the system voltage falls within the 4.2 V to 6.0 V operating range.

Part Context

The JLC1562B/D series serves as an I2C Bus I/O Expander designed to facilitate easy expansion of microcontroller interfaces. The device allows multiple units to be added to a single bus through unique address selection. It combines standard digital I/O functionality with analog features like a DAC and comparators, providing a versatile solution for interface management in compact designs.

Replacement Considerations

Direct substitutes include other variants within the JLC1562B family, such as JLC1562BN or JLC1562BF, provided the package type matches the design constraints. Cross-referencing pinouts and electrical characteristics with alternative I2C expanders is recommended to ensure compatibility with existing circuit layouts and software drivers.
