Learned List, On previous posts I was looking for a PDIP package 100 MHz decade divider. Reading just the front of the data sheet I thought that the 74LS161 would work. Boy, was I wrong. Several members posted that 25 Mhz max was its limit. So *on the road again* (sorry Willie) I went on another search this time with the correct logic family. It turns out Arrow carries the 74HC161 for less that $1. Additionally I D/L'd the Charles Wenzel Unusual Frequency Dividers PDF and discovered a 100 MHz decade divider circuit using 1/2 of a 74HC74 in a configuration that will decade divide up to 300 MHz. I'm attaching a copy of the circuit for anyone interested.
