Datasheet PDF of 538 KB labelled with literature code SDLS194. The name states no device, family or revision, so identify the part from the title page; SDLS codes are typical of Texas Instruments logic datasheets. Expect a pinout drawing, logic function description, recommended operating conditions and package dimensions. Repair technicians use this information to check logic levels in circuit, find supply pins and confirm a substitute fits. Verify the IC marking on the PCB matches the document before using it.
