CD4056BNSR

Display Drivers Overview

The CD4056BNSR is a CMOS BCD to 7-segment LCD decoder/driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and features a strobed-latch function for data retention. The device is housed in a 16-lead Small Outline (SOIC) package with a width of 5.30 mm. It supports dual-supply operation and includes built-in current sources suitable for driving liquid crystal displays. The component is designed for low power consumption, making it efficient for battery-operated applications.

Display Drivers Procurement Notes

Verify the specific suffix 'NSR' corresponds to the tape-and-reel packaging format required for your assembly process. Confirm that the 16-lead SOIC footprint matches your PCB design constraints. Ensure the operating voltage range aligns with your system's power supply specifications before integration.

Display Drivers Selection Notes

Select this component when a combined decoder and driver solution is needed for LCD applications. It eliminates the need for separate logic gates and buffer drivers. Consider the package size and thermal characteristics if high-density mounting is required. Verify compatibility with your microcontroller's BCD output signals.

Display Drivers Part Context

This part belongs to the CD4000 series of CMOS logic devices produced by Texas Instruments. The CD4056B variant specifically targets LCD driver applications, distinguishing itself from standard logic ICs by providing dedicated current sourcing for liquid crystal elements. It is part of a broader family of display controllers.

Display Drivers Replacement Considerations

Check for direct equivalents such as the CD4056BE or other variants within the CD4056B family. Ensure pinout compatibility and electrical specifications match before substitution. Consult official manufacturer documentation for cross-reference lists.
