DESCRIPTION
This is a vintage Texas Instruments integrated circuit in a 14-pin plastic DIP. It carries a house number rather than a standard TI catalog number.

Made in Malaysia, per the package marking
14-pin plastic DIP for through-hole mounting
Unused; the leads show light tarnish from storage
Compatibility:
Direct replacement only for equipment that calls for TI house number 239 2105. Match the house number exactly against the part you are replacing.
