MC14415 quad timer/driver is constructed with complementary MOS
enhancement mode devices. The output pulse width of each digital timer is
a function of the input clock frequency. Once the proper input sequence is
detected the output buffer is set (turned on), and after 100 clock pulses are
counted, the output buffer is reset (turned off).
The MC14415 was designed specifically for application in high speed line
printers to provide the critical timing of the hammer drivers, but may be used
in many applications requiring precision pulse widths.
