CD74HC4511PWRE4

Display Drivers Overview

The CD74HC4511PWRE4 is a high-speed CMOS BCD-to-7-segment latch/decoder/driver manufactured by Texas Instruments. It converts four-bit binary-coded decimal inputs into seven active-high outputs for driving displays. The device operates within a supply voltage range of 2 V to 6 V and features a propagation delay of 60 ns. It is housed in a 16-TSSOP package with an operating temperature range from -55 °C to +125 °C.

Display Drivers Feature Summary

• Converts four-bit BCD input codes into corresponding seven-segment display signals
• Includes internal latching capability to hold the decoded output state
• Provides active-high outputs suitable for direct LED segment driving

Display Drivers Applications

• Seven-segment LED numeric display systems
• Digital instrumentation readouts
• Consumer electronic indicator panels

Display Drivers Procurement Notes

Verify the component matches the specific RE4 suffix requirements for lead-free compliance and tape-and-reel packaging configuration. Confirm that the TSSOP-16 footprint aligns with the target PCB layout dimensions. Ensure the supply voltage constraints are compatible with the system design before procurement.

Display Drivers Selection Notes

Select this component when a BCD-to-7-segment decoder with integrated latching is required for low-power applications. The HC series offers faster switching speeds compared to standard 4000-series logic while maintaining low static power consumption. Consider the wide operating temperature range for industrial or automotive environments.

Display Drivers Part Context

This part belongs to the Texas Instruments CD74HC4511 family, which includes variants such as CD74HC4511PWR and CD74HC4511PWTE4. These devices share identical logical functionality but may differ in packaging options, environmental certifications, or reel specifications. The RE4 designation typically indicates specific manufacturing and compliance attributes defined by the manufacturer.

Display Drivers Replacement Considerations

The CD74HC4543E is documented as a similar replacement option within the same product category. Verify functional compatibility and pin alignment before substituting other decoders or drivers.
