Overview
The MIC5842YN is an 8-bit serial-input latched driver fabricated using BiCMOS technology. It operates in a single direction with rising-edge triggering and features sink-type output current flow. The device is housed in an 18-pin plastic DIP package, measuring 11.55mm in length, 7.52mm in width, and 2.26mm in height. It supports a supply voltage range of 4.5V to 5.5V and delivers up to 500mA of output current per channel. The component functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates 8-bit serial-to-parallel conversion with latched outputs for stable peripheral driving
- Utilizes BiCMOS fabrication to achieve high drive capability with low power consumption
- Provides robust transient protection on serial input lines to enhance signal integrity
Applications
- Driving LED displays and indicator arrays
- Controlling relay coils and solenoid actuators
- Peripheral interface circuits in industrial control systems
Procurement Notes
Verify the specific suffix 'YN' confirms the 18-pin Plastic DIP package variant. Confirm the manufacturer designation as Microchip Technology, formerly Micrel. Ensure the datasheet specifies the 4.5V to 5.5V operating voltage range and 500mA sink current capability. Check for RoHS compliance status if required by assembly specifications.
Selection Notes
Select this component when an 8-bit parallel output is required from a serial interface. The BiCMOS technology offers a balance of speed and drive strength suitable for moderate-frequency applications. The 500mA per-channel sink capability allows direct driving of loads without external transistors. Consider the DIP package form factor for through-hole mounting requirements.
Part Context
The MIC5842 is part of the MIC5841/5842 family of serial-input latched drivers. These devices are designed to replace discrete logic and driver combinations. The family utilizes BiCMOS technology to provide high-current outputs while maintaining compatibility with standard logic levels. This simplifies circuit design for peripheral control applications.
