MIC58P42YWM

Overview

The MIC58P42YWM is an 8-bit serial-input protected latched driver manufactured by Microchip Technology. It integrates eight CMOS data latches with a bipolar output stage capable of delivering 500mA per channel. The device operates within a supply voltage range of 5V to 12V and features high-voltage tolerance up to 80V on the outputs. Packaged in an 18-SOIC (Wide) case, it supports non-inverting logic operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates eight CMOS data latches with a bipolar output driver stage for high-current capability.
• Provides serial input interface for simplified control and data loading.
• Features protected outputs capable of handling high-voltage loads up to 80V.
• Supports non-inverting logic operation with latch functionality.

Applications

• Driving high-current inductive loads such as relays or solenoids
• Serial-to-parallel conversion in industrial control systems
• High-voltage load switching applications requiring latch retention

Procurement Notes

Verify the specific suffix YWM confirms the SOIC-18 wide package and tube packaging format. Confirm RoHS compliance status through official documentation. Ensure the operating temperature range meets system requirements of -40°C to +85°C. Check for moisture sensitivity classification if reflow soldering is planned. Validate that the 500mA output current rating aligns with the intended load specifications.

Selection Notes

Select this component when an 8-bit serial interface is required to drive high-current, high-voltage loads directly. The integrated latch function eliminates the need for external storage elements. Consider the 18-pin wide SOIC package for PCB layout constraints. Verify that the 5V to 12V supply range matches the system power architecture. Ensure the 500mA per-channel current capacity exceeds the maximum load current requirements.

Part Context

This part belongs to the MIC58P42 series of serial-input latched drivers from Microchip Technology. It is designed for applications requiring multiple high-current outputs controlled via a serial interface. The series typically includes variants with different packaging options, such as tube or reel formats, while maintaining identical electrical characteristics and functionality.

Replacement Considerations

Direct substitutes include other 8-bit serial latched drivers with comparable 500mA output current and 80V voltage ratings. Verify pin compatibility and package dimensions before substitution. Alternative parts must support the same 5V to 12V supply range and non-inverting logic configuration.
