Overview
The MIC58P42BN is an 8-bit serial-input protected latched driver manufactured by Microchip Technology. It features a bipolar output type and supports Strobe and Serial interfaces. The device operates with a load voltage range of 4.5V to 15V and provides a maximum output current of 500mA. Fault protection mechanisms include over-temperature and under-voltage lockout (UVLO). The component is housed in an 18-DIP package.
Feature Summary
- Provides 8-bit serial input data transfer via shift register logic
- Includes integrated fault protection for over-temperature and under-voltage conditions
- Offers latched output functionality for stable state retention
Applications
- LED lighting control systems
- Power distribution switching applications
- General-purpose latched driver circuits
Procurement Notes
Verify the specific package variant, as the MIC58P42 series includes both DIP and SOIC options. Confirm interface compatibility with standard TTL or DTL logic levels, which may require external pull-up resistors to ensure minimum logic high signals. Ensure the selected part matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component when an 8-bit serial interface with latched outputs is required. Consider the 18-DIP package for through-hole mounting needs. Evaluate the 500mA output capability against load requirements. Verify that the 4.5V to 15V operating range aligns with the system power supply. Check if built-in UVLO and over-temperature protection meet safety standards.
Part Context
The MIC58P42BN belongs to the MIC58P42 series of latched drivers from Microchip Technology. It shares functional similarities with other variants like the MIC58P42YN, which uses a surface-mount SOIC-18 package. The series is designed for reliable serial data handling and output latching in industrial and consumer electronics.
Replacement Considerations
The MIC58P42YN is a pin-compatible alternative within the same series, offering the same electrical functions but in an SOIC-18 narrow-body surface-mount package instead of the 18-DIP format.
