CD74HC4511EE4

Display Drivers Overview

The CD74HC4511EE4 is a high-speed CMOS BCD-to-7-segment decoder/driver manufactured by Texas Instruments. It features a 16-pin DIP package and operates within a supply voltage range of 2 V to 6 V. The device converts 4-bit binary-coded decimal inputs into seven segment outputs for driving common-cathode LED displays. Key electrical specifications include a propagation delay of 60 ns and an operating temperature range from -55 °C to +125 °C.

Display Drivers Feature Summary

• Integrates BCD-to-7-segment decoding with internal latch functionality for stable display output.
• Provides dedicated control pins for lamp test, blanking, and latch enable operations.
• Designed for direct interface with common-cathode LED numeric displays.

Display Drivers Applications

• Driving seven-segment LED numeric displays in digital instrumentation
• BCD code conversion for visual readouts in industrial control systems
• Display drivers in consumer electronic devices requiring decimal digit representation

Display Drivers Procurement Notes

Verify the specific EE4 suffix against the manufacturer's current documentation to confirm pinout compatibility and environmental compliance status. Ensure the DIP-16 package matches the target PCB footprint requirements. Cross-reference the datasheet revision date to validate electrical parameters against the design specifications before finalizing procurement orders.

Display Drivers Selection Notes

Select this component when a dedicated BCD-to-7-segment decoder with integrated latching is required for common-cathode LED applications. The HC series offers high-speed performance suitable for general-purpose logic interfaces. Consider the wide operating temperature range and robust CMOS input characteristics for environments with varying thermal conditions or noise susceptibility.

Display Drivers Part Context

This part belongs to the CD74HC4511 family of high-speed CMOS logic devices. It serves as a specialized decoder/driver within the broader category of encoders, decoders, multiplexers, and demultiplexers. The device is designed to simplify the interface between microprocessors or logic circuits and visual display units by handling both decoding and signal buffering functions.

Display Drivers Replacement Considerations

Compatible substitutes include the CD74HC4511PWR and CD74HC4511M96E4. Verify that alternative packages such as TSSOP or SOIC meet the physical mounting constraints if DIP is not mandatory. Ensure functional equivalence regarding latch behavior and output drive capabilities across different manufacturers.
