Frequently asked questions
Is TLV803EB29DBZR obsolete or end-of-life?
No. The part is listed as Active with no NRND or EOL status. It is safe for new designs and has no last-time-buy deadline.
What is the difference between TLV803 and TLV809?
Both are simple reset supervisors from TI. The TLV803 has an active-low open-drain output, while the TLV809 has an active-low push-pull output. The TLV803's open-drain output allows a different pull-up voltage and wired-OR connection; the TLV809's push-pull output does not require an external pull-up resistor.
