74 Series Logic

74 Series Logic

A range of classic 74 series logic chips from Silicon ARK

The older hard to find items are tested unused NOS ( New Old Stock ) in perfect condition.

Modern 74's will be NEW Stock and RoHS Compliant.

All varients are listed:  74xxx (original) , 74LSxxx (low power Schottky TTL) , 74HCxxx (high speed CMOS) , 74HTCxxx (HC version with LS TTL compatible inputs), 

So as to make one for one replacement selection easier we also list the same chips but by different manufacturers, for complete compatibility.

Power requirements: 74LS: 5V +/- 0.25V , 74HC: 2 to 6V   , 74HCT: 5V +/- 0.5V    HC and HCT devices are static sensitive.

To search for all the available options for a single device simply key in the basic number inthe top search box i.e  7401 .... 7474    or  74HC01, 74HC74      or 74LS01, 74LS74   .....
