HEF40174BP,652

Overview

The HEF40174BP,652 is a quadruple D-type edge-triggered flip-flop from the NXP HEF4000 series. It features four independent D-type flip-flops with separate clock inputs and complementary outputs (Q and Q_bar). The device operates on a single-ended input configuration within a supply voltage range of 4.5 V to 15.5 V. It utilizes a SOT-38 surface-mount package and supports an operating temperature range from -40°C to +85°C. Propagation delay is specified at 25 ns at 15 V.

Feature Summary

• Quadruple D-type edge-triggered flip-flop architecture
• Complementary output availability for each stage
• Single-ended input logic compatibility
• Surface-mount SOT-38 packaging

Applications

• Digital data storage circuits
• Shift register implementations
• Sequential logic control systems
• Binary counter modules

Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm RoHS compliance status via official documentation. Check current lifecycle status as components may be discontinued or subject to limited supply constraints. Ensure proper ESD handling procedures during storage and assembly.

Selection Notes

Select this component when requiring multiple independent D-type latching functions in a compact surface-mount form factor. Consider the 4.5 V to 15.5 V operating range for compatibility with standard CMOS logic levels. Evaluate the SOT-38 package dimensions against PCB layout constraints. Verify propagation delay requirements against system timing specifications.
