Learning the Art of Electronics, 2nd Edition
Parts List, Digital Labs 14 to 28 (includes Analog<=> Digital Lab) We have chosen the most common Mfgr. part number but in many instances parts with different prefixes and sufixes will work as well.
Updated 7/26/2025; Prices as of 2/2025 For example, we specified the Texas Instruments 74HC00N but their 74HC00AN or the CD7400EHC can both be substituted.
Indicates same part is on Analog Parts List You can also use a different manufacturer's part. Many parts are made by multiple companies and all are identical.
The 74HC00 is made by Toshiba as a TC74HC00APF, by National Inst. as the MM74HC00N and by onsemi as the MC74HC00AN.
