Phase-Frequency Detector
The MC12040 is a phase–frequency detector intended for use in systems
requiring zero phase and frequency difference at lock. In combination with a
voltage controlled oscillator (such as the MC1648, MC12147, MC12148 or
MC12149), it is useful in a broad range of phase–locked loop applications.

TRUTH TABLE
This is not strictly a functional truth table; i.e., it does not cover all possible
modes of operation. However, it gives a sufficient number of tests to
ensure that the device will function properly in all modes of operation.
