JLC1562BF

Overview

The JLC1562BF is an I2C Bus I/O Expander manufactured by onsemi, housed in a SOEIAJ-16 package. It provides an 8-bit bidirectional input/output port and a 6-bit resolution Digital to Analog Converter (DAC). The device supports up to eight units on a single bus via selectable 3-bit addresses. Operating conditions include a DC supply voltage range of 4.2 V to 6.0 V and an operating temperature range from -40°C to +85°C. The SCL clock frequency is limited to a maximum of 100 kHz.

Feature Summary

• I2C Bus interface with selectable 3-bit address for multi-device expansion
• Integrated 6-bit DAC with controllable threshold voltage
• Five comparators at inputs for external signal monitoring
• Open drain outputs with internal pull-up resistors on address pins

Applications

• System I/O expansion via I2C Bus
• Analog output generation using the integrated DAC
• External voltage level comparison and monitoring

Procurement Notes

Verify the specific ordering suffix 'F' corresponds to the SOEIAJ-16 package configuration as documented in the official datasheet. Confirm that the procurement specification aligns with the required rail shipping quantity of 50 units per package. Ensure compliance with the specified Pb-Free packaging requirements if applicable to the project standards.

Selection Notes

Select this component when an I2C-compatible solution is required for expanding general-purpose digital I/O lines. The inclusion of a 6-bit DAC allows for analog signal generation without external components. Verify that the system power supply falls within the 4.2 V to 6.0 V recommended operating range and that the thermal environment remains between -40°C and +85°C.

Part Context

This part belongs to the JLC1562B series of I2C Bus I/O Expanders produced by onsemi. The 'BF' designation specifically identifies the SOEIAJ-16 surface mount package variant. This series facilitates easy integration into systems requiring additional parallel I/O ports controlled through a serial two-wire interface.
