CD4033BNSR

Counter Dividers Overview

The CD4033BNSR is a CMOS decade counter and divider from the Texas Instruments CD4000B series, housed in a 16-pin SOIC surface-mount package. It features synchronous counting with asynchronous reset and provides decoded BCD outputs for direct driving of seven-segment displays. The device operates within a supply voltage range of 3 V to 18 V and supports a maximum clock frequency of 5 MHz at 10 V. It includes ripple clock-out capability for cascading multiple stages and functions across an industrial temperature range of -55°C to +125°C.

Counter Dividers Feature Summary

• Provides decoded BCD outputs compatible with common-cathode seven-segment displays
• Supports synchronous counting with asynchronous reset functionality
• Enables multi-stage expansion through ripple clock-out output

Counter Dividers Applications

• Digital countdown timers and clocks
• Frequency division circuits
• Seven-segment display drivers

Counter Dividers Procurement Notes

Verify the specific suffix 'NSR' confirms the SOIC-16 package and tape-and-reel orientation. Confirm RoHS compliance status as required by project specifications. Ensure the operating environment remains within the specified voltage and temperature limits defined in the official datasheet.

Counter Dividers Selection Notes

Select this component when a single-decade counter with direct display interface is required. It is suitable for applications needing low power consumption and wide voltage flexibility. Consider cascading multiple units if higher bit-counting or division ratios are necessary for the design.

Counter Dividers Part Context

This part belongs to the CD4000B family of CMOS logic devices, known for high noise immunity and broad operating voltage ranges. The CD4033 variant specifically integrates decoding logic, distinguishing it from raw binary counters like the CD4017 or CD4020. It serves as a standard building block for decimal counting applications in consumer and industrial electronics.

Counter Dividers Replacement Considerations

Compatible substitutes include the CD4033BE (PDIP package) and CD4033BM (SOIC package). Verify pin compatibility and electrical characteristics before substitution.
