MT8815AP1

Analog Switches - Special Purpose Overview

The MT8815AP1 is an 8 x 12 analog crosspoint switch array fabricated in ISO-CMOS technology. It features a 7 to 96 line decoder and latch circuits, allowing any of the 96 switches to be addressed via seven address bits. The device operates on a single supply voltage ranging from 4.5V to 13.2V, with separate digital ground (VSS) and negative analog reference (VEE) pins. It supports 12Vpp analog signals and maintains an on-state resistance of 65Ω max at VDD=12V and 25°C.

Analog Switches - Special Purpose Feature Summary

• Contains an 8x12 crosspoint switch array with integrated 7-to-96 line decoder and control latches
• Supports wide operating voltage range from 4.5V to 13.2V for flexible power integration
• Handles 12Vpp analog signals with low distortion and high isolation capabilities
• Features separate analog and digital reference supplies for optimized signal integrity

Analog Switches - Special Purpose Applications

• Key systems
• PBX systems
• Mobile radio
• Test equipment / instrumentation
• Analog/digital multiplexers

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type matches PLCC-44 specifications. Check datasheet revisions for updates regarding lead-free compliance and environmental certifications before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when an 8x12 analog switching matrix is required within a single IC. Ensure the application voltage stays within the 4.5V to 13.2V range. Consider thermal management if operating near maximum temperature limits. Verify pin compatibility with existing PCB layouts designed for PLCC-44 packages.

Analog Switches - Special Purpose Part Context

The MT8815 series belongs to Zarlink's analog crosspoint switch family, later acquired by Microchip Technology. This specific part number represents the lead-free, RoHS-compliant version housed in a 44-pin PLCC package. It serves as a direct replacement for older leaded variants like the MT8815AE1 in modern designs requiring environmental compliance.

Analog Switches - Special Purpose Replacement Considerations

The MT8815AE1 is a compatible alternative offering identical functionality in a 40-pin PDIP package. Ensure mechanical footprint differences are accounted for during board redesign. Both parts share the same electrical characteristics and pinout logic, facilitating straightforward migration between package types.
