CD40174BEG4

Overview

The CD40174BEG4 is a CMOS Hex D-Type Flip-Flop manufactured by Texas Instruments, belonging to the 4000B logic series. It integrates six independent D-type flip-flops within a single package, featuring positive-edge triggering and non-inverting outputs. The device operates on a supply voltage range of 3 V to 18 V and supports surface-mount installation in an SOIC-16 package. Key electrical parameters include a maximum propagation delay of 100 ns at 15 V with 50 pF load, a clock frequency of 16 MHz, and static current consumption of 4 µA. It functions reliably across an industrial temperature range from -55°C to +125°C.

Feature Summary

• Integrates six independent D-type flip-flops for high-density digital storage applications
• Features positive-edge triggering mechanism for precise synchronous data capture
• Provides non-inverting outputs compatible with standard CMOS logic levels
• Includes a master reset function to initialize all flip-flops simultaneously

Applications

• High-speed shift register configurations
• Parallel-to-serial data conversion circuits
• Digital state machine implementations
• Frequency division and counting logic stages

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS standards during sourcing. Confirm the package variant matches the required SOIC-16 footprint dimensions. Ensure the component status is active for long-term production planning. Cross-reference the manufacturer datasheet for exact pinout compatibility with existing PCB layouts.

Selection Notes

Select this component when multiple independent D-type storage elements are required in a compact form factor. The wide voltage range suits systems operating between 3 V and 18 V. Consider the 16 MHz clock limit for timing constraints. The industrial temperature rating ensures stability in harsh environments compared to commercial grade alternatives.

Part Context

This part belongs to the CD40174B family of hex D-type flip-flops. It serves as a fundamental building block for sequential logic circuits within the broader 4000B CMOS series. The device complements other logic families by providing reliable data retention and synchronization capabilities in complex digital designs.

Replacement Considerations

Direct substitutes include the CD40174BE and CD40174BNSR variants. These parts share identical logical functionality and pinouts but may differ in packaging or manufacturing origin. Verify electrical specifications match before substitution.
