CD4055BNSR

Display Drivers Overview

The CD4055BNSR is a CMOS liquid-crystal display driver manufactured by Texas Instruments, belonging to the 4000 series. It features a 16-lead small-outline integrated circuit (SOIC) package designed for surface-mount technology. The device functions as a BCD-to-seven-segment decoder and driver, specifically configured for one-digit seven-segment displays. It accepts binary-coded decimal inputs and provides decoded outputs suitable for driving common-cathode LCD segments. The component operates within a wide supply voltage range, supporting robust performance in various electronic applications requiring simple numeric display interfaces.

Display Drivers Feature Summary

• Decodes binary-coded decimal inputs into seven-segment outputs for direct display driving
• Designed specifically for single-digit common-cathode liquid-crystal displays
• Utilizes low-power CMOS technology compatible with standard logic families

Display Drivers Applications

• Numeric readouts on battery-operated portable instruments
• Simple digital counters and timers
• Consumer appliance control panels

Display Drivers Procurement Notes

Verify the specific suffix 'NSR' confirms the SOIC-16 surface-mount package and tape-and-reel quantity. Confirm RoHS compliance status through the official datasheet or manufacturer documentation. Ensure the application requires a common-cathode LCD configuration, as this driver is not suitable for LED displays. Cross-reference the part number with the latest Texas Instruments product selection guide to confirm current production status and availability.

Display Drivers Selection Notes

Select this component when a low-cost, single-digit LCD driver is required for BCD input systems. It is appropriate for designs prioritizing low power consumption and wide voltage operation over high-speed switching. Consider alternative drivers if multiple digits or LED compatibility is needed. Verify that the system's BCD source can drive the input capacitance of the CMOS gate without excessive delay.

Display Drivers Part Context

This part belongs to the CD4000B series of CMOS logic devices produced by Texas Instruments. It is functionally related to other display drivers like the CD4054B and CD4056B, which offer similar decoding capabilities but may differ in output characteristics or pin configurations. The NSR suffix indicates a specific packaging and reel format distinct from through-hole or smaller tube packages.

Display Drivers Replacement Considerations

Direct substitutes include the CD4054B and CD4056B from Texas Instruments, provided pin compatibility and output drive requirements match. Other manufacturers may offer equivalent CMOS BCD-to-seven-segment decoders, but verify logic levels and supply voltage ranges carefully.
