TTL Data Sheets (T.I.)

TI data sheets

Click the above link and then search by part number. For example, search for 74ls191. Then follow the link on the resulting screen to the data sheets in "pdf" format. Page 6 is the waveform page you will find useful.

TTL Data Sheets (Motorola)

These are the data sheets for many of the chips used in the ECES 301 lab. These data sheets are in Portable Document Format (pdf), you will need Adobe Acrobat Reader to display or print them. If you are on a CAEN workstation, everything should already be properly configured. If not then add the following MIME type to your helpers list:
