CD4511BE

Display Drivers Overview

The CD4511BE is a CMOS BCD-to-7-segment latch/decoder/driver manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 18V and features a low quiescent current of 40 nA. The device provides seven outputs for driving common-cathode displays, housed in a 16-pin DIP package. It supports an operating temperature range from -55°C to +125°C with a maximum power dissipation of 500 mW.

Display Drivers Feature Summary

• Integrates BCD latching, decoding, and driver functions into a single component
• Provides direct drive capability for common-cathode LED displays
• Includes lamp test and blanking control inputs for operational flexibility

Display Drivers Applications

• Driving common-cathode LED numeric displays
• BCD-to-decimal conversion in digital systems
• Seven-segment display interfaces in instrumentation

Display Drivers Procurement Notes

Verify the specific manufacturer datasheet for the CD4511BE to confirm pinout compatibility and electrical characteristics against design requirements. Ensure that the supply voltage remains within the specified 3V to 18V range during operation. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Display Drivers Selection Notes

Select this component when a combined latch, decoder, and driver solution is required for common-cathode displays. Consider the wide operating temperature range and low power consumption as key advantages for industrial or battery-powered applications. Verify that the load capacitance and current requirements of the display are within the output drive capabilities.

Display Drivers Part Context

This part belongs to the CD4000 series of CMOS logic devices produced by Texas Instruments. It is designed for general-purpose digital logic applications requiring reliable performance across a wide voltage and temperature range. The device complements other standard logic families by providing integrated display driving functionality.

Display Drivers Replacement Considerations

Compatible substitutes include the SN74LS47 for TTL-based designs, though interface differences exist. For CMOS replacements, consider the HEF4513B or MC14513B, which offer similar functionality but may have different pin configurations or electrical specifications.
