The LM3704XCBPX-308: The active-low, push-pull output drives the reset line directly without requiring an external pull-up resistor — the totem-pole stage sources and sinks the reset current to the downstream logic.
The part is marked RoHS non-compliant, so confirm the assembly house's exemption policy if the BOM requires full RoHS conformance.
The TL7702BID is a different part: it offers both active-high and active-low reset outputs with an open-drain stage, a 270ns typical propagation delay instead of a 140ms timeout, and comes in a DIP-8 or SOIC-8 package. The LM3704XCBPX-308 is a fixed-threshold, push-pull supervisor with a millisecond-level timeout — the two are not pin-compatible or drop-in replacements without a board spin.
Texas Instruments provides the datasheet and RoHS compliance data for the LM3704XCBPX-308. The part is marked RoHS non-compliant per the manufacturer's declaration.
