+Unknown 16-pin bare die found in my lab while imaging backlog. No idea of function, vendor, or original markings.
 Preliminary analysis:
   * 1-metal 1-poly CMOS process
   * Large "herringbone" structures are pad drivers
+  * Pad with trimmed corners is #1
+  * Pad above it is #16, Vdd
+  * Pad second from bottom on right is #8, Vss
+  * Inner ring is Vss
+  * Outer ring is Vdd
+  * Best guess so far is loadable 4-bit up/down counter, maybe 74HC or CD4000 series
