M74HC4543RM13TR

Display Drivers Overview

The M74HC4543RM13TR is a high-speed CMOS BCD-to-7-segment latch/decoder with an integrated LCD driver, manufactured by STMicroelectronics. It operates within the HCT logic series and features six internal circuits. The component is housed in a TSSOP-16 package and supports a maximum supply voltage of 5.5 V. This device decodes four-bit binary-coded decimal inputs to drive seven-segment displays, combining decoding functionality with display driving capabilities for efficient system integration.

Display Drivers Feature Summary

• Integrates BCD-to-7-segment decoding with dedicated LCD driver output stages
• Utilizes high-speed CMOS technology compatible with standard logic families
• Provides direct interface capability for liquid crystal display modules

Display Drivers Applications

• Liquid Crystal Display (LCD) segment drivers
• BCD-to-7-segment decoding interfaces
• Digital display systems requiring latch/decoder functionality

Display Drivers Procurement Notes

Verify the specific ordering suffix RM13TR against the manufacturer's official datasheet to confirm tape-and-reel packaging and pin configuration. Ensure compatibility with the target system's voltage levels and signal integrity requirements before procurement. Cross-reference the exact part number with authorized distributors to avoid counterfeit components.

Display Drivers Selection Notes

Select this component when a combined BCD decoder and LCD driver is required in a compact surface-mount package. Consider the TSSOP-16 form factor for space-constrained designs. Verify that the input logic levels align with the system's microcontroller or processor outputs to ensure reliable operation without additional level-shifting circuitry.

Display Drivers Part Context

This part belongs to the M74HC4543 family of BCD-to-7-segment latches/decoders. It is designed specifically for driving common-anode or common-cathode LCD segments. The device simplifies display interface design by integrating both decoding logic and output drivers into a single IC, reducing component count and board space compared to discrete solutions.

Display Drivers Replacement Considerations

Consult the official STMicroelectronics replacement guide for verified substitute part numbers. Generic equivalents may differ in electrical characteristics or pinout configurations. Do not assume cross-compatibility with other 74HC series devices without verifying functional equivalence.
