Key Features

  • Bidirectional binary or BCD counting mode selectable via a single pin, enabling versatile counter configurations without external logic
  • Presettable parallel load input allows counter to be initialized to any value, reducing system initialization time
  • CMOS 4000-series family compatibility ensures wide supply voltage range and low static power consumption suitable for battery-powered designs
  • TCO (Terminal Count Output) simplifies cascading multiple counters for wider counting ranges without additional glue logic

Applications

The CD4029BNSRE4 is widely used in digital systems requiring flexible counting, such as frequency dividers, event counters, and timer circuits in industrial control equipment. Its bidirectional binary/BCD count capability makes it suitable for up/down position tracking in motor control and automation applications. The presettable load feature also makes it ideal for programmable timer and sequencer designs in consumer electronics and embedded systems.

Frequently Asked Questions

What is the maximum operating frequency of the CD4029BNSRE4?

The CD4029BNSRE4 operates at a maximum clock frequency of 2 MHz (2,000,000 Hz) under nominal supply voltage conditions with a 50 pF load capacitance, making it suitable for moderate-speed counting applications in digital systems.

Does the CD4029BNSRE4 support both binary and BCD counting modes?

Yes, the CD4029BNSRE4 supports both binary and BCD (Binary-Coded Decimal) counting modes. The counting mode is selected via a dedicated pin, allowing the same IC to serve different applications without requiring separate components.

What package does the CD4029BNSRE4 come in and how many pins does it have?

The CD4029BNSRE4 is housed in a 16-pin Small Outline Package (SOP/SOIC), identified by JESD-30 code R-PDSO-G16. This surface-mount package is suitable for compact PCB designs and automated assembly processes.

Can the CD4029BNSRE4 be cascaded for wider counting ranges?

Yes, the CD4029BNSRE4 includes a TCO (Terminal Count Output) pin specifically designed for cascading multiple counters. This allows designers to build wider counters (e.g., 8-bit or 16-bit) by chaining multiple CD4029BNSRE4 devices together without additional logic gates.

Is the CD4029BNSRE4 RoHS compliant?

Yes, the CD4029BNSRE4 carries JESD-609 code e4, indicating it is a lead-free, RoHS-compliant device with a halogen-free option, meeting modern environmental regulations for electronics manufacturing.
