Key Features
- Wide supply voltage range of 3 V to 15 V allows operation across TTL-compatible and CMOS system voltages without re-design
- BCD rate multiplier function divides an input clock by any BCD-programmed value from 0 to 9, enabling flexible frequency synthesis in 16-pin DIP package
- CMOS technology provides very low quiescent current consumption, ideal for battery-backed and low-power timing circuits
- Standard DIP-16 through-hole package simplifies prototyping and repair in industrial control and legacy instrumentation applications
Applications
The CD4527BE BCD rate multiplier is commonly used in digital frequency division and clock generation circuits where a variable integer divisor between 0 and 9 must be set via BCD thumb-switches or microcontroller outputs. It suits industrial timer circuits, frequency synthesizers, and legacy instrument front panels that rely on decade-based frequency control. The wide 3 V to 15 V supply range also makes it compatible with both older TTL-level systems and modern 3.3 V CMOS logic designs.

Frequently Asked Questions
What supply voltage range does the CD4527BE support, and can it interface with both TTL and CMOS logic families?
The CD4527BE operates over a wide supply voltage range of 3 V to 15 V, which covers both the standard 5 V TTL and CMOS operating voltages as well as higher-voltage legacy industrial systems running at 12 V or 15 V. At 5 V its output levels are compatible with standard TTL logic, and at 3.3 V it interfaces well with modern CMOS microcontrollers, making it highly versatile for mixed-logic-family board designs.
How does the CD4527BE perform BCD rate multiplication, and what output frequencies can it generate from a reference clock?
The CD4527BE is a BCD rate multiplier that generates an output frequency equal to the input clock frequency multiplied by the BCD-programmed ratio from 0 to 9, divided by 10. For example, with a 100 kHz input clock and a BCD input of 7, the output is 70 kHz. This makes it useful for decade frequency synthesizers and precision timer circuits where the division ratio must be set with BCD DIP switches or a 4-bit BCD bus.
In what package does the CD4527BE come, and what are the advantages for prototyping or repair applications?
The CD4527BE is housed in a 16-pin DIP (Dual In-Line Package) with 2.54 mm pin pitch, making it directly insertable into standard breadboards and IC sockets. This through-hole format is preferred in prototyping labs and for field repair of legacy industrial equipment because the wide pin spacing allows easy manual soldering and desoldering, and 16-pin DIP sockets are universally available in electronic component stores worldwide.
When is the CD4527BE a practical alternative to a microcontroller for clock division tasks in an industrial design?
The CD4527BE is a practical alternative to a microcontroller in applications where a hardware-only, glitch-free frequency division by any single BCD digit (1 through 9) is required without firmware overhead or startup delay. Its quiescent current in CMOS technology is typically less than 1 µA at 5 V with no switching load, making it ideal for always-on timing circuits in industrial panel meters, legacy PLC modules, and process instrumentation where firmware updates are undesirable.
