MC14022BD

Counter Dividers Overview

The MC14022BD is a four-stage Johnson octal counter with built-in code converter manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an ambient temperature range from -55°C to +125°C. The device features eight decoded outputs that are normally low, going high only at their appropriate octal time period. Output changes occur on the positive-going edge of the clock pulse. It includes a carry out output for cascading and is capable of driving two Low-Power TTL loads or one Low-Power Schottky TTL load over the rated temperature range.

Counter Dividers Feature Summary

• Fully static operation allows for DC clock input circuits with slow rise times.
• Built-in carry out output facilitates cascading for expanded counting applications.
• Triple diode protection is provided on all inputs to guard against high static voltages.
• Outputs remain normally low and transition high only during their specific octal time period.

Counter Dividers Applications

• Frequency division applications
• Octal counter implementations
• Octal decode display systems

Counter Dividers Procurement Notes

Verify component authenticity through authorized distributors. Confirm package suffix matches SOIC-16 specifications. Check RoHS compliance status as standard versions may differ from Pb-Free variants. Validate date codes against current manufacturing availability. Ensure storage conditions adhere to specified humidity sensitivity levels.

Counter Dividers Selection Notes

Select this component for designs requiring a single-chip octal decoding solution. Verify power supply constraints fit within the 3V to 18V operational window. Consider the positive-edge triggering requirement for clock signals. Evaluate thermal management needs given the wide operating temperature range. Assess interface compatibility if driving TTL loads directly.

Counter Dividers Part Context

This part belongs to the MC14022B series, which represents a family of CMOS octal counters. The 'D' suffix specifically denotes the SOIC-16 surface-mount package variant. It serves as a pin-for-pin replacement for the CD4022B in existing designs. The series utilizes a Johnson counter architecture to generate decoded outputs without external logic gates.

Counter Dividers Replacement Considerations

MC14022BDG is a direct Pb-free replacement within the same manufacturer line. CD4022BNSR from Texas Instruments is listed as a similar alternative. Verify pinout compatibility before substituting with cross-manufacturer parts.
