Product Overview

The MT8816AF1 is a low-power CMOS analog crosspoint switch originally designed by Zarlink and now supported by Microchip. It integrates an 8 × 16 non-blocking analog matrix to connect any of 8 Y input channels to 16 X output channels. Built-in 7-bit address decoder with latches lets MCUs set/clear cross-point links via digital bus commands. It features low RON, flat frequency response and low crosstalk for precision analog and telecom signal switching. Housed in TQFP-44 (10×10mm), it delivers compact matrix routing for telecom switches, audio/video mixers, ATE and data acquisition backplanes.

Core Advantages

8 × 16 Non-Blocking Crossbar Routing Matrix

Provides a highly dense switching topography that supports simultaneous independent connections between any input and output pins, significantly cutting layout trace routing overhead.

Integrated Address Latches and Digital Decoders

Embeds data storage control registers and binary decoding networks straight onto the silicon die, allowing direct interfacing with common CPU data buses without requiring external latch ICs.

Ultra-Low Distortion and Crosstalk Performance

Utilizes proprietary internal design shielding techniques to suppress inter-channel cross-coupling and high-frequency feedthrough, ensuring excellent signal integrity for noise-sensitive audio and communication applications.

Wide Analog Signal Dynamic Range

Supports analog signal levels up to the full split or single supply rail boundary values (e.g., VDD to VEE), maintaining uniform impedance metrics without structural clipping or voltage drop clipping errors.

Frequently Asked Questions

Q1: Is your currently available stock of the MT8816AF1 switch 100% genuine and original?

A: Yes, we guarantee that all MT8816AF1 integrated circuits in our stock are 100% brand-new, factory-original products. Every shipment lot undergoes strict inspection tracking controls and is dispatched securely inside original anti-static PLCC trays to ensure perfect physical pin integrity.

Q2: How does the address latch operation work in the MT8816AF1 to control individual cross-points?

A: The MT8816AF1 uses a 7-bit addressing protocol consisting of 4 bits for X-address selection and 3 bits for Y-address selection. To connect a specific cross-point, the microprocessor writes the coordinates to the address lines, sets the DATA pin high, and pulses the Strobe input. The internal latch holds this state, allowing the processor to free the bus while the connection remains intact.

Q3: Can this device safely handle both single-ended and split dual-rail voltage configurations?

A: Yes. The MT8816AF1 can run on a single supply rail configuration by tying the VEE ground terminal reference to 0V. For bi-polar analog signal sweeps (e.g., standard audio signals swinging above and below zero volts), VEE can be connected to a negative voltage rail down to -7V, provided the overall potential difference between VDD and VEE does not exceed the absolute limit of 13.2V.

Q4: How can our physical engineering group get formal component engineering drawings or request bulk wholesale pricing tiers?

A: Please complete the Quick Inquiry form on this webpage with your target quantities. Our application support desk will process your technical and supply criteria and reply with full data assets within 24 hours.
