74HC4511N,652

Overview

The 74HC4511N,652 is a BCD to 7-segment latch/decoder/driver manufactured by Nexperia (formerly NXP). It features latch storage for BCD inputs and dedicated blanking and lamp test inputs. The device is designed to drive common cathode LED displays with a guaranteed 10 mA drive capability per output. It operates within a supply voltage range of 2 V to 6 V and supports through-hole mounting in a DIP-16 package. The component functions as a high-speed Si-gate CMOS logic IC compliant with JEDEC standards.

Feature Summary

• Provides latch storage for Binary-Coded Decimal inputs to maintain display data stability.
• Includes dedicated control inputs for display blanking and lamp testing functions.
• Capable of driving common cathode LED displays with sufficient output current.
• Offers pin compatibility with legacy 4000B series devices for design continuity.

Applications

• Driving seven-segment LED displays
• Driving incandescent displays
• Driving fluorescent displays

Procurement Notes

Verify the manufacturer status carefully, as Nexperia has separated from NXP. Confirm that the specific suffix indicates the correct packaging and compliance specifications required for your assembly process. Ensure the component meets all relevant environmental regulations applicable to your region before finalizing procurement plans.

Selection Notes

Select this component when a dedicated decoder with input latching is required for direct LED interface. It eliminates external latching logic, simplifying circuit design. Verify that the load current requirements do not exceed the specified drive capability per segment. Consider the operating temperature range and supply voltage constraints relative to the target application environment.

Part Context

This part belongs to the 74HC/HCT logic family, known for high-speed CMOS operation. It serves as a functional replacement for older 4000B series decoders while offering improved performance characteristics. The device integrates decoding, latching, and driving capabilities into a single integrated circuit, reducing board space and component count in display driver applications.

Replacement Considerations

Check for pin-compatible alternatives such as the HEF4511B or other 74HC4511 variants from different manufacturers. Ensure electrical parameters like output current and supply voltage ranges match the original design requirements before substituting.
