CD4054BNSR

Display Drivers Overview

The CD4054BNSR is a CMOS LCD driver manufactured by Texas Instruments, designed for driving four-segment liquid crystal displays. It operates within a supply voltage range of 3 V to 18 V and features a maximum clock frequency of 8 MHz. The component is housed in a surface-mount SOIC-16 package and supports an operating temperature range from -55 °C to +125 °C. It includes internal latch functionality for data retention and draws a maximum power supply current of 100 µA.

Display Drivers Feature Summary

• Integrates BCD-to-LCD decoding with internal latch capability for simplified interface control
• Supports direct driving of four-segment LCD displays without external logic components
• Operates reliably across extended industrial temperature ranges

Display Drivers Applications

• Four-segment LCD display modules in instrumentation
• Digital readout interfaces for consumer appliances
• Industrial control panel indicators

Display Drivers Procurement Notes

Verify the suffix 'NSR' confirms the SOIC-16 surface mount package and tape-and-reel shipping format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 3 V to 18 V supply voltage range and check that the 8 MHz clock limit meets system timing requirements.

Display Drivers Selection Notes

Select this component when a dedicated decoder-driver for four-segment LCDs is required. It eliminates the need for separate decoding logic gates. Consider the SOIC-16 package constraints for PCB layout. Verify that the input signal levels are compatible with the chosen CMOS logic family voltage levels.

Display Drivers Part Context

This part belongs to the CD4054B series of CMOS LCD drivers. It serves as the surface-mount reel variant of the CD4054BE through-hole device. The series provides integrated decoding and driving capabilities for simple numeric or alphanumeric LCD segments within standard CMOS logic families.

Display Drivers Replacement Considerations

The CD4054BE is a verified pin-compatible alternative offering identical functionality in a PDIP-16 through-hole package.
