-These 3-terminal regulators allow any normal voltage to be generated so long as it's above 1.25 and about 2V below the input voltage; two resistors is seen as a small price to pay and the formula is simple. These regulators drop less than....

This chip is for FSK and/or FM data reception. It would allow simple, low component count modems. The Bipolar internals would give less spreads than CMOS. However: - the measured phase noise which is directly bad on FM and FSK because....

The 4013 is often used in toggle mode with not Q tied to D. The tolerance to slowly rising signals on the clock inputs is dependent on the chip manufacturer. RCA has the best with Schmitt inputs on both clocks. Other manufacturers don't ....

Some devices have only a Zener diode connected to pin 15 whilst other devices bring out a third phase comparator. Compare the NXP and Fairchild device datasheets as an example.....
