CD4054BPW

Display Drivers Overview

The CD4054BPW is a CMOS LCD driver manufactured by Texas Instruments, designed to drive one digit of a four-segment liquid crystal display. It operates within a supply voltage range of 3 V to 18 V and features a low power consumption profile with a maximum supply current of 100 µA. The device dissipates up to 500 mW of power and supports a maximum clock frequency of 8 MHz. It is housed in a 16-pin Plastic Small Outline (PSOP) package suitable for surface-mount applications. The component functions reliably across an extended temperature range from -55 °C to +125 °C.

Display Drivers Feature Summary

• CMOS technology ensures low power consumption and high noise immunity for battery-operated systems.
• Directly drives one-digit, four-segment LCD displays without requiring external multiplexing circuitry.
• Wide operating voltage range accommodates various single-supply configurations.

Display Drivers Applications

• Battery-powered digital meters
• Portable electronic devices with LCD interfaces
• Industrial control panels requiring segment displays

Display Drivers Procurement Notes

Verify the specific suffix 'PW' confirms the PSOP-16 surface-mount package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration. Ensure the design accounts for the specified 500 mW power dissipation limits under worst-case thermal conditions.

Display Drivers Selection Notes

Select this component when a single-chip solution is required for driving a simple four-segment LCD in space-constrained designs. Compare against the CD4054BE if through-hole mounting is preferred. Verify that the 8 MHz clock limit meets the system timing requirements for display updates.

Display Drivers Part Context

This part belongs to the CD4054B family of LCD drivers from Texas Instruments. It serves as a specialized interface between logic circuits and liquid crystal displays, simplifying the design of alphanumeric or numeric readouts in consumer and industrial electronics.

Display Drivers Replacement Considerations

The CD4054BPWRG4 is listed as a discontinued alternative; verify availability of active substitutes such as the CD4054BE for through-hole needs or other PSOP variants from the same manufacturer series.
