CD4056BME4

Display Drivers Overview

The CD4056BME4 is a CMOS BCD to 7-Segment LCD Decoder/Driver with a Strobed-Latch Function. It operates within a supply voltage range of 3 V to 18 V and supports a maximum clock frequency of 8 MHz. The device features a power dissipation rating of 500 mW and a maximum operating current of 300 µA. It is housed in a 16-pin SOIC package and functions across an extended temperature range from -55 °C to +125 °C.

Display Drivers Feature Summary

• Converts Binary-Coded Decimal inputs into seven-segment displays for liquid crystal indicators
• Integrates a strobed-latch function to manage display data timing
• Utilizes low-power CMOS technology for efficient operation

Display Drivers Applications

• Driving single-digit seven-segment LCD displays
• BCD decoding in digital instrumentation panels
• Consumer electronic display interfaces requiring latch functionality

Display Drivers Procurement Notes

Verify the component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm the package type matches the required SOIC-16 footprint and ensure the temperature grade aligns with operational requirements. Cross-reference the ordering suffix to confirm lead-free compliance and specific tape-and-reel or tube packaging details as defined by Texas Instruments documentation.

Display Drivers Selection Notes

Select this component when a dedicated decoder-driver with integrated latching is required for LCD applications. Ensure the design accommodates the specified 3 V to 18 V supply range and that the PCB layout supports the SOIC-16 thermal characteristics. Verify that the 8 MHz clock limit meets the system's update rate requirements without exceeding the 500 mW power dissipation threshold.

Display Drivers Part Context

This part belongs to the Texas Instruments CD4056B series, which includes variants such as the CD4056BE and CD4056BM. These devices are standard CMOS logic components designed specifically for driving multiplexed or static LCD segments. The 'E4' suffix typically indicates environmental compliance and specific manufacturing lot attributes within the broader CD4056 family.

Display Drivers Replacement Considerations

Direct substitutes include the CD4056BE and CD4056BM. Verify pin compatibility and electrical parameters before substitution.
