CD4527BMS

CMOS BCD Rate Multiplier

December 1992

Features

Description

• High Voltage Type (20V Rating)

• Cascadable in Multiples of 4-Bits

• Set to “9” Input and “9” Detect Output

• 100% Tested for Quiescent Current at 20V

• 5V, 10V and 15V Parametric Ratings

CD4527BMS is a low power 4-bit digital rate multiplier that

provides an output pulse rate which is the clock input pulse

rate multiplied by 1/10 times the BCD input. For example,

when the BCD input is 8, there will be 8 output pulses for

every 10 input pulses. This device may be used to perform

arithmetic operations (add, subtract, divide, raise to a

power), solve algebraic and differential equations, generate

natural logarithms and trigonometric functions, A/D and D/A

conversion, and frequency division.

• Maximum Input Current of 1µA at 18V Over Full Pack-

age Temperature Range; 100nA at 18V and +25^oC

For fractional multipliers with more than one digit,

CD4527BMS devices may be cascaded in two different

modes: the Add mode and the Multiply mode (see Figures 9

and 11). In the Add mode,

• Noise Margin (Over Full Package/Temperature Range)

- 1V at VDD = 5V

- 2V at VDD = 10V

- 2.5V at VDD = 15V

Output Rate =

(Clock Rate) [0.1BCD1 + 0.01BCD2 + 0.001BCD3 + . . .]

• Standardized Symmetrical Output Characteristics

• Meets All Requirements of JEDEC Tentative Standard

No. 13B, “Standard Speciﬁcations for Description of

‘B’ Series CMOS Devices”

In the Multiply mode, the fraction programmed into the ﬁrst

rate multiplier is multiplied by the fraction programmed into

the second one,

e.g.

or 36 output
