MIC5822YN

Overview

The MIC5822YN is an 8-bit serial-in latched driver manufactured by Microchip Technology, designed for power distribution and load driving applications. It features a single circuit with one input line and nine output lines, configured as a non-inverting latch within the TTL logic series. The component supports through-hole mounting in a PDIP-16 package, operating within a supply voltage range of 5V to 12V and a temperature range of -40°C to +85°C. With a maximum output current of 0.5A and a typical operating supply current of 4.5mA, it provides reliable control for bipolar loads without integrated diodes.

Feature Summary

• Serial-to-parallel conversion capability via 8-bit shift register architecture
• Latched output state retention independent of input signal continuity
• Bipolar drive configuration suitable for controlling external switching elements
• Robust thermal performance across extended industrial temperature ranges

Applications

• Industrial motor control systems requiring precise phase sequencing
• Power distribution units managing multiple load channels
• Automotive electronics utilizing high-current latch drivers
• Consumer appliances needing reliable serial interface control

Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates detailed requirements rather than explicit exemption. Confirm moisture sensitivity level (MSL) handling procedures during storage and assembly to prevent damage. Ensure the specific variant matches the required bipolar drive characteristics and absence of internal diodes. Cross-reference the PDIP-16 package dimensions against PCB footprint specifications to guarantee mechanical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a serial interface is preferred over parallel inputs to reduce pin count. Choose the MIC5822YN for applications requiring latched outputs that maintain state after clock pulses cease. Consider its 500mA output capability for driving moderate loads directly or via external transistors. Evaluate the 5V to 12V supply range against system power availability. Opt for this part over MIC5821 if bipolar drive functionality is specifically required for the application.

Part Context

Part of the MIC582x family of serial-in latched drivers from Microchip Technology. Designed to replace older Micrel-branded equivalents while maintaining functional compatibility. Offers a cost-effective solution for expanding I/O capabilities in embedded systems. Provides a standardized interface for controlling multiple discrete loads through a minimal number of microcontroller pins.

Replacement Considerations

MIC5822BN is a direct substitute but is discontinued; verify availability constraints.

FAQ

Does the MIC5822YN include internal flyback diodes?

No, the MIC5822YN is specified as having no internal diodes, requiring external protection for inductive loads.

What is the logic polarity of the MIC5822YN outputs?

The outputs are non-inverting, meaning the output state follows the input data sequence directly.
