Small package decade counter?
rcbuck:
Does anyone know of a small package decade counter? I need to divide a 100 Hz signal by 10. The smallest units I can find are in SOIC-14 or SOIC-16.
Nexperia has a new line of fixed division counters, the 74AHC1G421x series, but unfortunately no divide by 10.
DC1MC:
GreenPak SLG46536V 50c in STQFN-14 (2.0 x 2.2 mm)
Ian.M:
If you don't want to go down the GreenPak road, you could program a PIC10F part in SOT23-6 or DFN-8 (2.0 x3.0 mm) to do the job (PIC10F200 if you can tolerate the propagation delay of doing it in software, or PIC10F320 to use its CLC if you need minimal delay), then order them preprogrammed from MicrochipDirect for production.
oPossum:
74HC4017 is available in a 2.5 x 3.5 mm DHVQFN package.
rcbuck:
The GreenPak and and DHVQFN solutions are too small to solder by hand. I can't tolerate the propagation delay of a PIC. Looks like I will have to use a 74HC4017 in a TSSOP package. Thanks for the suggestions.
