CD4033BF3

Display Drivers Overview

The RCA CD4033BF3 is a CMOS decade counter and divider integrated circuit belonging to the 4000B series. It features a five-bit binary ripple counter with decoded seven-segment display outputs for direct driving of common cathode displays. The device operates on a single power supply ranging from 3 V to 18 V and includes asynchronous reset, clock inhibit, and ripple carry functions. Packaged in a ceramic dual-in-line format, it supports positive edge triggering and up-counting direction, suitable for digital counting applications requiring robust performance across wide temperature ranges.

Display Drivers Feature Summary

• Provides decoded seven-segment display outputs for direct interface with visual indicators
• Features asynchronous reset input to clear all flip-flops independently of the clock signal
• Includes clock inhibit and ripple carry outputs for cascading multiple stages

Display Drivers Applications

• Digital frequency counters and dividers
• Seven-segment display drivers for numeric readouts
• Timekeeping circuits in clocks and timers

Display Drivers Procurement Notes

Verify component authenticity by checking manufacturer markings against official RCA or Intersil datasheets. Confirm package type matches the specified ceramic DIP configuration. Ensure voltage ratings align with system requirements before integration. Cross-reference part numbers with current distributors to avoid obsolete stock issues.

Display Drivers Selection Notes

Select this component when a decade counter with built-in display decoding is required. Compare with similar models like CD4026 if different output configurations are needed. Consider power supply constraints and operating temperature limits during design. Verify compatibility with existing logic families in the circuit.

Display Drivers Part Context

This device is part of the extensive 4000B series of CMOS logic ICs originally developed by RCA. The series offers high noise immunity and low power consumption compared to earlier TTL technologies. The CD4033 variant specifically targets applications needing direct display interfacing without additional decoding logic.

Display Drivers Replacement Considerations

Compatible substitutes include CD4033BE from Texas Instruments and CD4033BD from Renesas. Verify pinout compatibility and electrical specifications before substitution. Check for any differences in package dimensions or thermal characteristics.
