MIC5821BN

Overview

The MIC5821BN is an 8-bit serial-input latched driver manufactured by Microchip Technology. It features a single circuit with nine output lines and operates in a non-inverting polarity configuration. The device is housed in a PDIP-16 package and supports through-hole mounting. It functions within a supply voltage range of 5 V to 12 V and maintains operation between -40°C and +85°C. The component draws a working power current of 4.5 mA and belongs to the TTL logic series.

Feature Summary

Serial input architecture for simplified control interface
Latching functionality for stable output states without continuous signaling
High-current drive capability suitable for various load types

Applications

Driving relays and solenoids
LED array control
Transformer drivers for isolated power supplies

Procurement Notes

Verify the manufacturer origin, as this part was originally developed by Micrel Semiconductor before acquisition by Microchip Technology. Confirm the specific suffix 'BN' corresponds to the PDIP-16 package variant. Ensure compliance with RoHS directives and check humidity sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when an 8-channel latching solution is required for driving inductive or high-current loads. It is appropriate for applications needing serial data input to reduce pin count compared to parallel drivers. Consider the PDIP-16 package constraints for PCB layout and thermal management relative to the specified operating temperature range.

Part Context

The MIC5821BN is part of the MIC5821 family of 8-bit serial-input latched drivers. This series provides a cost-effective method for controlling multiple outputs using minimal microcontroller pins. The device integrates shift register and latch functions to maintain output states independently of the input signal after latching.
