Battery backup supervisor for 5V MPU rails
Housed in an 8-pin PDIP (0.300" body) with through-hole mounting, this part is a direct fit for legacy industrial controllers, PLC I/O modules, and telecom equipment where a 5V rail must ride through brief mains interruptions without corrupting SRAM or losing configuration registers.
It remains a current-production item, which means the usual franchised and independent channels both carry it.
Where it sits in the cycle
For a mature supervisor IC in an 8-pin DIP package, the supply-demand balance is stable. This is not a part that sees allocation spikes or spot-premium surges — it is a commodity monitor with a long production tail. The independent channel holds inventory from overstocked OEM contracts and franchise redistributions, so availability tends to be steady even when lead times stretch on newer SMD supervisors. The procurement decision here is about BOM continuity and RoHS policy, not shortage-cycle timing.
