IC is 24 pins, 600mils wide, 5v. Installing the IC backwards WILL destroy it. The IC has been fully tested, and comes with no warranty. Due to age, we can not warranty how long it should last or work correctly.

This IC can be installed on the Mockingboard and Phasor sound cards and produce extraordinary sound effects and human-like speech. This is how the IC was tested. You can replicate testing using the sound card’s Demo Disk to locally test and use the IC.

**IC pictured is for display purposes and you will receive the equivalent TDK branded 78A263A speech IC.** All ICs are the same internally. Votrax’s tech (die) stock was sold off to different companies over the years, and they produced (encapsulated) ICs under their brands.
