CD4511BNSR

Display Drivers Overview

The CD4511BNSR is a CMOS BCD-to-7-segment decoder/driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and features four binary inputs with seven segment outputs. The device supports LED displays and includes latch, blanking, and ripple-blank control functions. It is housed in a 16-SOIC surface-mount package and operates across an extended temperature range from -55 °C to +125 °C.

Display Drivers Feature Summary

• Converts 4-bit BCD input signals into decoded outputs for driving 7-segment LED displays.
• Integrates internal latches to store input data independently of the display state.
• Provides dedicated control pins for lamp test, blanking, and ripple-blank operations.

Display Drivers Applications

• Digital clock and timer display drivers
• Numeric readouts for measurement instruments
• Status indicators in industrial control panels

Display Drivers Procurement Notes

Verify that the ordering suffix 'NSR' corresponds to the SOIC-16 surface-mount package and tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the component meets the specified operating temperature range requirements for the intended application environment before finalizing procurement.

Display Drivers Selection Notes

Select this component when a surface-mount BCD-to-7-segment decoder is required for space-constrained designs. It is suitable for applications needing integrated latching and low static current consumption. Ensure the design accommodates the specific pinout and thermal characteristics of the SOIC-16 package.

Display Drivers Part Context

This part belongs to the Texas Instruments CD4000/CD4500 series of CMOS logic devices. It serves as a specialized decoder within this family, designed specifically for interfacing digital logic with visual output devices. The NSR variant denotes the surface-mount implementation compatible with automated assembly processes.

Display Drivers Replacement Considerations

The CD4511BE is a verified through-hole replacement option offering identical logical functionality. Verify package compatibility and pin alignment when substituting between surface-mount and through-hole variants.
