NLV14020BDR2G

Counter Dividers Overview

The NLV14020BDR2G is a 14-stage ripple-carry binary counter constructed with MOS P-Channel and N-Channel enhancement mode devices. It advances the count on the negative-going edge of the clock pulse. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc and features diode protection on all inputs. Buffered outputs are available from stages 1 and 4 through 14, while stage 2 and 3 remain unbuffered. It includes a common reset line and is designed for fully static operation.

Counter Dividers Feature Summary

• Features a 14-stage asynchronous ripple-carry binary counting architecture.
• Includes input wave shaping circuitry and diode protection on all inputs.
• Provides buffered outputs from specific stages for driving loads.

Counter Dividers Applications

• Time delay circuits
• Counter controls
• Frequency-dividing circuits

Counter Dividers Procurement Notes

Verify that the NLV prefix confirms AEC-Q100 qualification and PPAP capability requirements are met for automotive or controlled change applications. Confirm the SOIC-16 package type matches the design footprint. Ensure the ordering suffix corresponds to the tape and reel shipping format specified in the manufacturer documentation.

Counter Dividers Selection Notes

Select this component when a high-stage binary counter is required for frequency division or timing control. The wide supply voltage range supports various logic families. Verify that the asynchronous ripple nature meets the timing constraints of the system, as propagation delays accumulate across the 14 stages.

Counter Dividers Part Context

This part belongs to the MC14020B series of 14-bit binary counters. The NLV prefix indicates it is qualified for automotive applications and requires unique site and control change requirements compared to standard commercial versions. It serves as a pin-for-pin replacement for the CD4020B.

Counter Dividers Replacement Considerations

The datasheet identifies the CD4020B as a pin-for-pin compatible alternative. Designers should verify if the standard commercial version meets the specific automotive qualification (AEC-Q100) and PPAP requirements mandated by the NLV prefix.
