74HC4511FPEL-E

Overview

The Renesas Electronics Corporation 74HC4511FPEL-E is a BCD-to-seven-segment latch/decoder/driver belonging to the HC/UH logic series. It integrates a 4-bit storage latch, a decoder, and output drivers in a single package. The device accepts Binary-Coded Decimal inputs and drives common-cathode LED displays. Key control inputs include Lamp Test (LT), Blanking (BI), and Latch Enable (LE). It operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates 4-bit storage latch functionality for stable data retention during display updates
• Provides direct decoding of BCD inputs to seven-segment display signals
• Includes dedicated Lamp Test and Blanking inputs for display diagnostics and brightness control

Applications

• Driving common-cathode seven-segment LED numeric displays
• Digital clock and timer circuits requiring stable digit representation
• Industrial control panels with status indication requirements

Procurement Notes

Verify the specific suffix 'FPEL-E' against the manufacturer's current product status documentation. Confirm that the lead time and availability align with project schedules, as electronic components may undergo lifecycle changes or obsolescence notices without prior widespread announcement. Ensure the ordering information matches the exact package type and tape/reel specifications required for automated assembly processes.

Selection Notes

Select this component when a combined latch and decoder function is required to reduce board space and simplify timing design. The HC series offers high-speed operation suitable for general-purpose digital systems. Consider the 2 V to 6 V operating range compatibility with the system's power supply rails. Verify that the output drive capability meets the current requirements of the connected LED segments without external buffering.

Part Context

This part belongs to the Renesas 74HC4511 family of BCD-to-seven-segment decoders. Similar variants include HD74HC4511P and HD74HC4511RPEL, which share identical logical functions but differ in packaging formats such as DIP or SOIC. The FPEL-E designation typically indicates a specific surface-mount package configuration and reel packaging standard used by the manufacturer for high-volume production environments.

Replacement Considerations

Compatible substitutes include the HD74HC4511FPEL and HD74HC4511RPEL from Renesas/Hitachi. Cross-manufacturer equivalents like the CD74HC4511 from Texas Instruments or HCF4511B from STMicroelectronics offer pin-compatible alternatives with similar electrical characteristics.
