CD4055BMT

Display Drivers Overview

The CD4055BMT is a CMOS liquid crystal display driver manufactured by Texas Instruments, designed for driving one digit of a seven-segment display. It accepts Binary-Coded Decimal (BCD) inputs and provides decoded outputs suitable for LCD segments. The device operates within a supply voltage range of 3V to 18V and features a low supply current of 40 nA. It is housed in a 16-SOIC surface-mount package with a width of 3.90mm. The component supports an operating temperature range from -55°C to 125°C and complies with RoHS3 standards.

Display Drivers Feature Summary

• Decodes BCD inputs to drive seven-segment LCD displays
• Operates with low power consumption suitable for battery applications
• Supports wide supply voltage ranges for flexible system integration

Display Drivers Applications

• Seven-segment digital display drivers
• LCD indicator modules
• Consumer electronic instrumentation panels

Display Drivers Procurement Notes

Verify the specific suffix 'BMT' against the manufacturer's official documentation to confirm tape-and-reel packaging and lead-free status. Confirm that the component meets RoHS3 requirements as specified in the latest datasheet. Ensure compatibility with existing PCB footprints for the 16-SOIC package before procurement.

Display Drivers Selection Notes

Select this component when a single-digit seven-segment LCD driver is required with BCD input capability. Consider the 16-SOIC package constraints and the -55°C to 125°C temperature range for environmental suitability. Verify that the 3V to 18V supply voltage aligns with the target system design.

Display Drivers Part Context

This part belongs to the CD4055B family of CMOS logic devices produced by Texas Instruments. It is functionally related to other display drivers like the CD4054B but offers seven-segment decoding capabilities. The series is designed for general-purpose logic and display applications requiring low power and high noise immunity.

Display Drivers Replacement Considerations

The CD4055BM is listed as a direct substitute. Verify pinout and electrical specifications match the original design requirements before substitution.
