74HCT4511D,652

Overview

The 74HCT4511D,652 is a BCD to 7-segment latch/decoder/driver manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features four address inputs (A, B, C, D), a latch enable input (LE), a ripple blanking input (BI), and a lamp test input (LT). The device provides seven segment outputs (a to g) with a guaranteed drive capability of 10 mA per output for common cathode LED displays. It is housed in a 14-SOIC package.

Feature Summary

• BCD to 7-segment decoding with latch storage functionality
• Direct driving capability for common cathode LED displays
• Includes dedicated control inputs for lamp testing and blanking

Applications

• Driving common cathode LED numeric displays
• Digital display systems requiring BCD input conversion
• Consumer electronics with numerical readouts

Procurement Notes

Verify component authenticity through authorized Nexperia distributors or certified partners. Confirm the specific suffix matches the required package and tape/reel specifications. Check current lifecycle status as availability may vary. Ensure compliance with relevant environmental directives such as RoHS before integration into final products.

Selection Notes

Select this component when TTL-compatible logic levels are required for BCD-to-LED interfacing. It is suitable for designs needing integrated latching and high-current drive capabilities without external transistors. Consider the 14-SO package constraints for PCB layout. Verify that the 5V operating voltage aligns with the system power supply.

Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices from Nexperia. It is functionally compatible with other 74HCT family members but specifically designed for decoder applications. The 'D' suffix indicates the SOIC package type, while ',652' denotes the specific packaging configuration provided by the manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers include 74HCT4511D,653.
