MT8812AE1

Analog Switches - Special Purpose Overview

The MT8812AE1 is an analog crosspoint switch array fabricated in ISO-CMOS technology, featuring an 8 x 12 matrix of switches. It integrates a 7-to-96 line decoder and latch circuits for addressing any of the 96 switches via seven input bits. The device supports a wide operating voltage range from 4.5 V to 14.5 V and handles 14Vpp analog signals. Key electrical parameters include a maximum on-state resistance (RON) of 65 Ω at VDD=14V and 25°C, with a resistance matching specification (ΔRON) of ≤10 Ω. It offers high off-state isolation of -95 dB feedthrough and low total harmonic distortion of 0.01%.

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the 40-pin PDIP format. Ensure the ordering suffix corresponds to lead-free matte tin construction as specified in the ordering information section of the documentation.

Analog Switches - Special Purpose Selection Notes

Select this component when an 8 x 12 analog switch matrix is required within a single IC. Consider the 4.5 V to 14.5 V supply range and 14Vpp signal capability for compatibility with system voltage levels. Evaluate the 65 Ω maximum RON and -95 dB isolation against circuit requirements for signal integrity and loss.

Analog Switches - Special Purpose Part Context

Originally manufactured by Zarlink Semiconductor Inc., this part is now associated with Microchip Technology following industry acquisitions. The MT8812 series represents a family of analog crosspoint switches, with the AE1 variant specifically denoting the 40-pin plastic DIP package configuration suitable for through-hole mounting applications.

Analog Switches - Special Purpose Replacement Considerations

Consult official Microchip or Zarlink documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical parameter equivalence before implementation.
