CD4055BPW

Display Drivers Overview

The CD4055BPW is a CMOS LCD driver manufactured by Texas Instruments, belonging to the 4000B logic series. It features a 16-pin TSSOP surface-mount package and contains two independent circuits per chip. The device operates with a supply voltage range of 3 V to 18 V and supports a BCD interface for driving one digit of a seven-segment display. It functions within an operating temperature range of -55 °C to 125 °C and utilizes rising-edge triggering for data input.

Display Drivers Feature Summary

• Provides dedicated drive capabilities for single-digit seven-segment LCD displays
• Accepts Binary-Coded Decimal (BCD) inputs for direct segment control
• Integrates dual independent circuits within a compact surface-mount package

Display Drivers Applications

• Driving single-digit seven-segment LCD indicators in consumer electronics
• Interface modules requiring BCD-to-LCD translation
• Low-power portable devices utilizing CMOS logic families

Display Drivers Procurement Notes

Verify the specific suffix 'BPWR' against official Texas Instruments documentation to confirm tape-and-reel packaging and exact pinout configuration. Ensure the component matches the 4000B series specifications regarding voltage tolerance and thermal limits before integration into designs requiring wide operational ranges.

Display Drivers Selection Notes

Select this component when a dedicated LCD driver with BCD compatibility is required for single-digit applications. It is suitable for designs needing robust CMOS performance across extreme temperatures. Consider package constraints and voltage requirements relative to the system's power supply architecture.
