The -12 suffix indicates 120ns; faster than the -20 and -15 (200 & 150ns) parts and therefore can usually substitute for all these.
Faster than 4164-200, 4164-20, 4164-150, & 4164-15.
Also, commonly used across a series of arcade machines such as the popular WPC game boards. Use these original parts to avoid any hassles with compatibility & timing problems.
Remember, if the other guys don't state that their parts are *NEW*, well then guess what... (-:
Don't be fooled.... "New" parts don't have scratches & rusted spotty pins on them.... at least the ones over here don't. Get your parts from people who know how to handle electronic components - you'll be glad you did.
These chips are shipped in their original ESD approved tubes (cut to order for package fit). At no time during packaging are these chips touched by human hands. They are "poured" from one tube into another and taped shut - that's it. We ship from NY and we ship quick. Smaller quantity packages ship out via USPS First Class parcel w/ delivery confirmation. Larger order packages (over 13oz) ship out via USPS Priority Mail with tracking confirmation. If you have any questions about anything just email me - I check email several times a day and I always respond. You can email me weekdays & weekends - I'm almost always around. If I'm here, I'll write you back immediately. Techguy127.
