Overview
The MIC5821YN is an 8-bit serial-input latched driver manufactured by Microchip Technology. It utilizes BiCMOS technology and operates within a supply voltage range of 5 V to 12 V. The device features a single circuit with one input line and nine output lines, housed in a PDIP-16 package for through-hole installation. It functions as a non-inverting TTL logic latch with rising-edge triggering. The component supports a maximum operating current of 4.5 mA and is rated for temperatures between -40 °C and +85 °C.
Feature Summary
- Serial-to-parallel conversion capability via serial input and latched outputs
- BiCMOS technology providing flexibility beyond standard logic buffers
- Non-inverting output polarity for direct signal driving
Applications
- General-purpose latch driver circuits
- Industrial control systems requiring serial data expansion
- Embedded systems needing parallel output generation from serial inputs
Procurement Notes
Verify the manufacturer designation, as Micrel was acquired by Microchip Technology. Confirm the PDIP-16 package type and through-hole mounting style match your PCB design requirements. Ensure the 5 V to 12 V supply voltage range aligns with your system power rails. Check for RoHS compliance status if environmental regulations apply to your project.
Selection Notes
Select this component when an 8-bit parallel output is required from a serial interface. The BiCMOS technology offers performance advantages over standard logic families. Consider the PDIP-16 package constraints for board space. Verify that the 4.5 mA operating current fits within your power budget. Ensure the temperature range meets your operational environment specifications.
Part Context
This part belongs to the MIC5821/MIC5822 family of 8-bit serial-input latched drivers. The MIC5821 series specifically denotes the version without internal diodes. These devices are designed to replace standard logic buffers where higher drive capability and serial interface integration are needed. The family leverages BiCMOS technology for improved performance characteristics compared to older discrete solutions.
Replacement Considerations
The MIC5822YN is a related part within the same family, sharing identical electrical specifications and pinout configuration. Both parts function as 8-bit serial-input latched drivers with no internal diodes. Verify package compatibility and manufacturer documentation before substitution.
