MT8816AF1

Analog Switches - Special Purpose Overview

The MT8816AF1 is an ISO-CMOS analog switch array manufactured by Microchip Technology, designed for telecommunications applications. It features an 8x16 cross-point switching matrix with a single functional channel configuration. The device operates on a single supply voltage ranging from 4.5V to 13.2V or dual supplies of ±4.5V. Key electrical parameters include a maximum on-resistance of 65 ohms and a -3dB bandwidth of 45MHz. It is housed in a 44-TQFP surface-mount package and functions within a temperature range of -40°C to 85°C.

Analog Switches - Special Purpose Feature Summary

• Integrates internal control latches and address decoder for simplified interface timing
• Supports wide operating voltage ranges including 12Vpp analog signal capability
• Utilizes full CMOS switch architecture to minimize distortion and feedthrough

Analog Switches - Special Purpose Applications

• Telecommunications switching systems
• Signal routing in test and measurement equipment
• Cross-point switching matrices

Analog Switches - Special Purpose Procurement Notes

Verify component status as the MT8816AF1 is listed as obsolete. Confirm availability through authorized distributors or surplus channels. Check RoHS compliance status, noting it meets ROHS3 specifications. Validate packaging details against current stock conditions, as standard packaging quantities may vary for end-of-life items.

Analog Switches - Special Purpose Selection Notes

Select this component when an 8x16 analog cross-point switch is required for telecom infrastructure. Ensure the design supports the specified 4.5V to 13.2V single supply or ±4.5V dual supply rails. Verify that the 44-TQFP package footprint fits the PCB layout constraints. Consider the 65-ohm on-resistance limit for signal integrity requirements in the target application path.

Analog Switches - Special Purpose Part Context

This part belongs to the MT8816 family of ISO-CMOS analog switch arrays. It shares core architectural features with variants like the MT8816AP, which also utilizes a 44-pin plastic leaded chip carrier package. The family is characterized by internal decoding logic and low-distortion CMOS switching technology suitable for high-frequency signal routing.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate the MT8816AP for pin compatibility, though verify lead-free status differences. Cross-reference with other Microchip ISO-CMOS cross-point switches if the specific 8x16 matrix is unavailable.
