SN74HCT74: SN74HCT74PWT’s footprint for PCB

user4979899

Part Number: SN74HCT74

Hi Sir,

I would like to ask about SN74HCT74PWT’s footprint for PCB. In datasheet Page 18 is the footprint of the actual IC, not for PCB.
What I means footprint for PCB is like the picture below and is on Page 17.
Or did SN74HCT74D and SN74HCT74PW have the same footprint for PCB which means the picture below is also available for SN74HCT74PW?
Thanks.

Hi Anne,
D and PW packages do not have the same footprint. They have different pin pitches and package dimensions, which are all listed in the datasheet.

I would recommend using the Ultra Librarian software to directly download the footprint you need. The files are available here: www.ti.com/.../pinout-quality
