I could use some suggestions from electronics geeks.

I've got a need to control two active-low inputs to a buffer IC in an 'exclusive' fashion: only one of them can be low at any moment in time. I've already got pull-up and pull-down resistors to ensure that they start that way during powerup.

I'd been planning on just connecting them to a pair of GPIOs from the microcontroller, but I'm concerned that during reset, if the normally-low pin was being driven high, there will be a short time when both inputs will be low as the MCU outputs move to high-Z... I can't guarantee that the reset in the MCU will cause both pins to go to high-Z simultaneously.

Is there a straightforward circuit I can drive from a single GPIO to generate a low signal on one of two outputs in a 'break-before-make' style (to abuse an old relay term)?

The reason that I need to do this is that two of the buffer's outputs are connected to two of its inputs, so if both control inputs are low at once that will generate a circular connection and I have no idea how the buffer chip will behave.

Just ordered parts for a very (very) old project of mine. I started this well over a decade ago to support a platform of different display types for clocks (my time nut phase.) It's unfortunately large to fit that format I had before. Moved from a PIC18 to an ESP32-S2-Mini and hoping to get back to my Nixie Tube Clock project. (Don't bother to google as never published it).

(Tagging electronics folks, feel free to respond or not as willing/able.)

I'm doing initial research to design a custom battery mgmt/charge/balance circuit for a prototype. 4S/5S LiPo (nonprotected), 90Wh, 12A discharge. It needs to run the device while charging, like a laptop.

Any advice or resources on circuits/architecture/ICs, key safety req's? I'm a professional circuit designer but not experienced w/Li batteries.

Thanks!
