74HC4511P-E

Overview

The Renesas Electronics Corporation 74HC4511P-E is a BCD-to-seven-segment latch/decoder/driver belonging to the HC/UH series. It integrates a 4-bit storage latch, a decoder, and output drivers for seven-segment displays. The device operates within a supply voltage range of 2 V to 6 V and supports surface mount or through-hole installation depending on the specific package variant. It features low input current and low quiescent supply current characteristics suitable for general-purpose logic applications.

Feature Summary

• Integrates 4-bit storage latch functionality with BCD-to-seven-segment decoding
• Provides direct drive capability for common-cathode seven-segment LED displays
• Includes dedicated control inputs for lamp test, blanking, and latch enable operations

Applications

• Digital display systems requiring stable BCD to seven-segment conversion
• Consumer electronics utilizing numeric readouts
• Industrial control panels with status indication displays

Procurement Notes

Verify the exact suffix against the manufacturer's official documentation to confirm pin compatibility and electrical specifications. Ensure the selected variant matches the required package type and operating temperature range for the target application environment.

Selection Notes

Select this component when a combined latch and decoder solution is required for driving seven-segment indicators. Consider the HC series speed and voltage characteristics relative to the system's power budget and signal timing requirements.

Part Context

This part belongs to the widely used 74HC logic family, known for high-speed CMOS operation. The 4511 function code specifically denotes a BCD-to-seven-segment decoder with latch capabilities, distinguishing it from standard decoders or multiplexers in the same series.

Replacement Considerations

Compatible substitutes include CD74HC4511 and HD74HC4511 variants from other manufacturers, provided pinouts and electrical parameters are verified.
