JLC1562BN

Overview

The JLC1562BN is an I2C Bus I/O Expander manufactured by onsemi, housed in a PDIP-16 package. 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 SCL clock frequency up to 100 kHz. It features five comparators at inputs P0-P4, with address selection via three pins (A0-A2) allowing for multiple devices on the same bus.

Feature Summary

• I2C Bus interface with selectable 3-bit address
• Integrated 6-bit DAC output
• Five input comparators with programmable thresholds
• Open drain outputs with power-down protection

Applications

• Remote I/O expansion in embedded systems
• Analog threshold monitoring via integrated comparators
• Low-voltage signal generation using internal DAC

Procurement Notes

Verify the component marking matches the specified alphanumeric code for the PDIP-16 variant. Confirm the package suffix corresponds to the required lead form and ensure the ordering information aligns with the specific tube quantity requirements for assembly processes.

Selection Notes

Select this component when an 8-bit I/O expander with analog capabilities is required. Ensure the system voltage falls between 4.2 V and 6.0 V. Verify that the I2C bus speed does not exceed 100 kHz and that the open-drain output configuration meets the load requirements.

Part Context

This part belongs to the JLC1562B series of I2C Bus I/O Expanders from onsemi. It is designed to facilitate easy expandibility for microcontroller systems, allowing multiple units to be added to a single I2C bus through hardware address selection.

Replacement Considerations

Check for direct pin-compatible alternatives within the JLC1562B family, such as the SOEIAJ-16 packaged variants (e.g., JLC1562BF), if board space constraints require a surface-mount solution instead of the through-hole PDIP-16 package.
