What are the key features of CD4089BE?
- Binary rate multiplier function generates output pulse rates that are binary fractions of the input clock, enabling programmable frequency division from 1/2 to 255/256 of the source frequency
- TCO (Terminal Count Output) pin facilitates cascading multiple CD4089BE devices to extend multiplication depth beyond 8 bits without external logic
- Wide supply voltage range of the 4000-series CMOS family (3 V to 18 V) permits direct interfacing with both TTL and CMOS logic systems in the same design
What is CD4089BE used for?
The CD4089BE is used in frequency synthesis, programmable clock generation, and digital frequency division circuits where a binary fraction of a reference clock must be produced. It is also employed in industrial timing controllers, digital waveform generators, and legacy telecommunications equipment that rely on 4000-series CMOS logic for reliable, low-power frequency scaling at up to 1.2 MHz.

Frequently Asked Questions
What is the maximum operating frequency of the CD4089BE binary rate multiplier?
The CD4089BE operates at a maximum frequency of 1.2 MHz (1,200,000 Hz) with a 50 pF load capacitance. At lower supply voltages the maximum frequency decreases; for example at 5 V supply the speed is lower than at 15 V, which is characteristic of the 4000-series CMOS process used in this device family.
How does the binary rate multiplier function of the CD4089BE differ from a standard frequency divider?
A standard divider produces only integer division ratios (divide by 2, 4, 8, etc.), whereas the CD4089BE binary rate multiplier produces an output pulse count equal to N/256 of the input frequency, where N is programmable from 0 to 255. This allows non-power-of-two frequency ratios such as 100/256 or 200/256, essential for audio sample rate conversion, stepper motor speed control, and digital phase-locked loops.
Can multiple CD4089BE devices be cascaded to achieve higher-resolution rate multiplication?
Yes, the CD4089BE includes a TCO (Terminal Count Output) pin specifically for cascading. By connecting the TCO of one device to the clock input of a second device, designers achieve 16-bit rate multiplication with resolution of 1/65536, suitable for precision frequency synthesis in test equipment operating at input clock rates below 1.2 MHz.
What supply voltage range does the CD4089BE support, and how does it interface with 5 V TTL logic?
As part of the 4000-series CMOS family, the CD4089BE operates from 3 V to 18 V supply. When powered at 5 V it is directly compatible with 74HC-series CMOS logic; interfacing to standard 5 V TTL requires only that the CD4089BE output current, typically 0.5 mA at 5 V, is sufficient to drive the 1.6 mA TTL input, which can be resolved by adding a 74HC buffer in the signal path.
