Housed in an 8-pin PDIP through-hole package, this part suits legacy board designs, prototyping, or applications where through-hole assembly is preferred. The commercial temperature range (0°C to 70°C) covers typical indoor equipment, office electronics, and benchtop instrumentation.
That means no last-time-buy window to manage, no forced redesign for a replacement.
The MAX690TCPA is functionally the same device as the base MAX690 — same battery backup circuit, same active-low reset, same 3.075V threshold. The 'TCPA' suffix designates the 8-PDIP package and commercial temperature range. It is a direct drop-in for any MAX690 in the same package and temperature grade.
