MC14527B Datasheet (Motorola) - BCD Rate Multiplier

MC14527B, BCD Rate Multiplier

MOTOROLA SEMICONDUCTOR TECHNICAL DATA 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
