Product details

The 3V to 18V supply range is the headline feature of this part. It means the CD4077BNSR can run directly from a 3.6V lithium cell, a 5V logic rail, a 12V automotive battery, or an unregulated 15V supply in industrial equipment — no separate regulator needed. This simplifies the power tree and reduces BOM cost in multi-voltage designs. The 1 µA max quiescent current ensures negligible standby drain, critical for battery-powered instruments or always-on monitoring circuits.

Propagation delay and speed considerations

The maximum propagation delay is 100 ns at 15V supply with a 50 pF load. This is typical for 4000B CMOS — the family trades speed for wide voltage range and low power.

The 4000B series has been in production for decades, and TI continues to support it, so long-term supply is stable.

Frequently asked questions

What is the propagation delay of CD4077BNSR?

This is typical for the 4000B CMOS family and is adequate for control and status logic paths below 10 MHz.

Is CD4077BNSR RoHS compliant?

Yes, the CD4077BNSR is ROHS3 compliant.

Can CD4077BNSR be used as a replacement for CD4077B?

The CD4077BNSR is a surface-mount variant of the CD4077B logic function. The 'NSR' suffix indicates the 14-SOIC package. If the original CD4077B was in a different package (e.g., DIP), verify the footprint compatibility before substitution. The logic function and electrical characteristics are identical.
