MT8815AE1

Analog Switches - Special Purpose Overview

The MT8815AE1 is an 8 x 12 analog switch array fabricated in ISO-CMOS technology. It features a 7 to 96 line decoder and latch circuits for addressing any of the 96 switches. The device operates on a wide supply voltage range from 4.5V to 13.2V, supporting 12Vpp analog signals with a maximum on-resistance of 65Ω at VDD=12V. It utilizes separate analog and digital reference supplies (VDD, VEE, VSS) and is housed in a 40-pin PDIP package.

Analog Switches - Special Purpose Feature Summary

• Contains an 8x12 crosspoint switch array with integrated address decoding and latching
• Supports wide operating voltage ranges up to 13.2V with low power consumption
• Provides high isolation and minimal feedthrough/crosstalk between channels
• Features separate analog and digital ground references for flexible signal handling

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 integrity and pin alignment against the 40-pin PDIP specification. Review datasheet revision history for updates regarding lead-free compliance and manufacturing changes prior to integration.

Analog Switches - Special Purpose Selection Notes

Select this component when an 8x12 analog matrix is required within a 40-pin DIP footprint. Ensure the design accommodates separate VDD, VEE, and VSS supplies if negative analog signal switching is necessary. Verify that the 65Ω max on-resistance meets system impedance requirements.

Analog Switches - Special Purpose Part Context

This part belongs to the MT8815 family of analog crosspoint switches manufactured by Zarlink Semiconductor, now part of Microchip Technology. It serves as a legacy alternative to newer CMOS switch matrices, offering a specific 8x12 configuration suitable for telecommunications and audio routing applications requiring high channel density in a standard DIP package.

Analog Switches - Special Purpose Replacement Considerations

The MT8815AP1 is a PLCC-44 variant of the same functional device. Direct pin-to-pin replacement is not possible due to the different package types (PDIP vs. PLCC). Evaluate PCB layout modifications or adapter solutions if transitioning between these package styles.
