Hey guys!
I recently acquired a super old racing clock and am trying to replace the motherboard with my own stuff. I’m loosely following another guy I found after some googling who documented his findings really well on his blog https://radagast.ca/arduino/signalex1.html
The problem is thatches guy is utilizing the MIC5801BN (datasheethttps://www.mouser.com/datasheet/2/268/ … 181000.pdf)
From what I can tell, this is an old IC that is completely obsolete.
Could someone help me find a suitable replacement IC? I would love to find one that has a smaller form factor since it would save me some PCB space - these things are huge!
It doesn’t have to work exactly like this MIC5801. I can always change the code / structure of the circuit.
The MIC5800/5801 latched drivers are high-voltage, high- current integrated circuits comprised of four or eight CMOS data latches, a bipolar Darlington transistor driver for each latch, and CMOS control circuitry for the common CLEAR, STROBE, and OUTPUT ENABLE functions.
Thanks so much!
