MT8815APR1

Analog Switches - Special Purpose Overview

The MT8815APR1 is an analog switch array fabricated in ISO-CMOS technology, featuring an 8 x 12 matrix of crosspoint switches. It includes a 7-to-96 line decoder and latch circuits for addressing any of the 96 switches via seven address bits. The device operates on a wide supply voltage range from 4.5V to 13.2V and supports 12Vpp analog signals. It utilizes separate analog and digital reference supplies (VDD, VEE, VSS) and offers low power consumption with minimal feedthrough and crosstalk.

Analog Switches - Special Purpose Feature Summary

• Internal control latches and address decoder for efficient switching
• Full CMOS architecture designed for low distortion applications
• Separate analog and digital reference supplies for flexible operation

Analog Switches - Special Purpose Applications

• Key systems
• PBX systems
• Mobile radio

• Analog/digital multiplexers

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and lead condition upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Review datasheet specifications for absolute maximum ratings to prevent operational damage during integration.

Analog Switches - Special Purpose Selection Notes

Select this component when an 8 x 12 analog crosspoint configuration is required within a single IC. Consider the PLCC-44 package format for surface mount assembly. Evaluate the wide operating voltage range and separate supply pins if negative analog signal handling or distinct digital/analog grounding is necessary for the specific circuit design.

Analog Switches - Special Purpose Part Context

This part belongs to the MT8815 series of analog switch arrays manufactured by Zarlink Semiconductor Inc., now part of Microchip Technology. The 'APR1' suffix indicates a 44-pin PLCC package supplied in tape and reel format. The device is RoHS compliant and Pb Free Matte Tin.

Analog Switches - Special Purpose Replacement Considerations

The MT8815AP1 serves as a tube-packaged equivalent. Verify pin compatibility and electrical characteristics against the MT8816AP if a different channel count is acceptable. Consult official documentation for any discontinued variants or updated family members.

Analog Switches - Special Purpose FAQ

How are the switches controlled?

Switches are controlled by selecting one of the 96 memory locations using seven address bits (AX0-AX3, AY0-AY2). Data is written asynchronously when the STROBE input is high and latched on the falling edge.

What is the function of the RESET pin?

A logical high on the RESET input asynchronously returns all memory locations to logical zero, turning off all crosspoint switches simultaneously.

Can VSS and VEE be connected together?

Yes, the VSS and VEE pins can be tied together if a single voltage reference is sufficient for the application, though they are provided separately to enable switching of negative analog signals.
