SN74HC244: PCN#20250520000.0

Part Number: SN74HC244
Other Parts Discussed in Thread: SN54HC244

Tool/software:

Next PCN of Texas Instruments, which is a total mess …

  1. PCN letter affected products page missing most of the products mentioned later in the table
  2. The change description in the revision history is completely useless and wrong.
  3. Recommended operating temperature for SN74HC244 is still +85°C
  4. Low power consumption (maximum) stated in the datasheet header 80µA but the specification got changed in the electrical characteristics of SN74HC244

  5. The "new" characteristics of the SN74HC244 are copied from the SN54HC244.
  • What happened here?
  • What is the intention of these adoptions?
  • If the recommended operating temperature is or gets adopted to +125°C
    • What is the key difference from the SN54HC244?
    • What will be the specification for the SN74HC244 at +85°C?
  • Have there been changes to the die, manufacturing, testing, or packaging in the last 2 years?
