CD4511BF

Display Drivers Overview

The CD4511BF is a 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 open-drain outputs capable of driving common-cathode LED displays directly, with a maximum output current of 6.8 mA. It includes dedicated control inputs for lamp test, blanking, and latch functions. The component is housed in a 16-pin DIP package and supports an operating temperature range from -55°C to 125°C.

Display Drivers Feature Summary

• Integrates BCD decoding logic with display driver capabilities for direct LED interface
• Includes internal latching mechanism to maintain display data without continuous input
• Provides dedicated control pins for lamp testing, signal blanking, and data storage

Display Drivers Applications

• Driving common-cathode 7-segment LED numeric displays
• Digital counter readout interfaces
• Numeric display systems in industrial instrumentation

Display Drivers Procurement Notes

Verify the specific suffix 'BF' against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the source document explicitly lists this exact part number variant rather than generic family members. Confirm RoHS compliance status and lead-free certification through verified datasheets prior to procurement.

Display Drivers Selection Notes

Select this component when a high-voltage CMOS decoder is required to drive common-cathode LEDs directly. It is suitable for applications needing internal data retention via the latch function. Consider the wide operating voltage range and extended temperature specifications for robust environmental performance.

Display Drivers Part Context

The CD4511 belongs to the standard CD4000 series of CMOS logic devices. It serves as a specialized decoder/driver designed specifically for interfacing binary-coded decimal signals with visual display units. This series is widely utilized in digital electronics for converting binary data into human-readable numerical formats on LED panels.

Display Drivers Replacement Considerations

Compatible alternatives include the CD4511BE (DIP-16) and CD4511BNSR (SOIC-16). Verify pin configuration and package dimensions before substitution.
