MIC5842YWM

Overview

The MIC5842YWM is an 8-bit serial-input latched driver manufactured by Microchip Technology. It utilizes BiCMOS logic technology and operates within a temperature range of -40°C to +85°C. The device features a single function with eight output lines, housed in an 18-pin Wide Small Outline Integrated Circuit (SOIC W) package measuring 11.55 mm in length, 7.52 mm in width, and 2.26 mm in height. It supports serial-to-serial/parallel operation modes with unidirectional data flow triggered on the rising edge. The component is designed for sink current output and includes transient protection capabilities.

Feature Summary

• Provides 8-bit serial input with parallel latched outputs for peripheral driving applications
• Utilizes BiCMOS logic technology for robust performance
• Features built-in transient protection for enhanced reliability
• Supports sinking output current configuration

Applications

• Peripheral driver circuits requiring serial data conversion
• Industrial control systems utilizing BiCMOS logic interfaces
• Electronic equipment operating within extended temperature ranges

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct package type and temperature rating. Confirm that the requested variant matches the required pin count and logical functionality. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and technical specifications before procurement.

Selection Notes

Select this component when an 8-bit serial-to-parallel interface is required with latched outputs. Ensure the application demands BiCMOS logic compatibility and sinking output drivers. Verify that the 18-pin SOIC W package fits the board layout constraints and that the operating temperature range meets environmental requirements.

Part Context

This component belongs to the MIC584x series of serial-input latched drivers produced by Micrel, now part of Microchip Technology. The series includes variants such as the MIC5841, offering similar functionalities with different bit depths or configurations. These devices are designed for interfacing microcontrollers with peripheral loads using minimal I/O pins.

Replacement Considerations

Check for MIC5841 variants if fewer bits are sufficient. Verify pinout compatibility with other 18-pin wide SOIC drivers. Consult Microchip's official substitution guide for direct replacements.
