It's a cheap "programmable counter/divider" - 16 pin standard DIL package. The 4636 can be "programmed" (by applying a 4-bit binary number to the inputs A,B,C,D) to divide by 1,2,3,4,5,6,7....16. Downside: Because of the odd ratio, the output won't have 50% duty cycle. But a simple LC filter can restore a "clean" signal. 73, Wolf DL4YHF. |
