BCD Rate Multiplier
The MC14527B BCD rate multiplier (DRM) provides an output pulse rate
based upon the BCD input number. For example, if 6 is the BCD input
number, there will be six output pulses for every ten input pulses. This part
may be used for arithmetic operations including multiplication and division.
Typical applications include digital filters, motor speed control and frequency
synthesizers.
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Output Clocked on the Negative Going Edge of Clock
• Strobe for Inhibiting or Enabling Outputs
• Enable and Cascade Inputs for Cascade Operation of Two or More
DRMs
• “9” Output for the Parallel Enable Configuration and DRMs in Cascade
