WD2143M Four-Phase Clock Generator

The WD2143 Four-Phase Clock Generator is a MOS/LSI device capable of generating four phase clocks. The ouput pulse widths are controlled by tying an external resistor to the proper control inputs. All pulse widths may be set to the same width by tying
the ?PW line through an external resistor. Each pulse width can also be individually programmed by tying a resistor through the appropriate +1PW-,4PW control inputs.
