ON Semiconductor MC14543BDR2 Product Overview

The ON Semiconductor MC14543BDR2 is a versatile and high-performance BCD-to-Seven Segment Latch/Decoder/Driver designed for use in 7-segment display applications. This integrated circuit is engineered to directly drive a 7-segment display with very low power consumption and high noise immunity. It is suitable for a wide range of applications in the consumer, automotive, and industrial markets where a reliable and efficient display driver is required.

With its built-in latch, decoder, and driver functionalities, the MC14543BDR2 simplifies the process of converting binary coded decimal (BCD) inputs into the corresponding 7-segment display outputs. The device is capable of driving LEDs and other display technologies, making it an excellent choice for digital clocks, meters, and other electronic devices that require numeric displays.

The MC14543BDR2 comes in a small-outline 16-pin package, making it space-efficient for modern compact electronic designs. It operates over a wide voltage range from 3V to 18V, providing flexibility in various power environments. This feature, combined with its low power consumption, makes the device particularly well-suited for battery-operated equipment.

Key features of the MC14543BDR2 include lamp test provision, leading/trailing zero suppression, and a blanking input pin. The lamp test feature allows for a quick check of all display segments to ensure they are functioning correctly. Leading and trailing zero suppression helps in displaying cleaner numeric values without unnecessary zeros, enhancing readability. The blanking input can be used to turn off the display, which is useful for power-saving modes or when the display is not required to be active at all times.

ON Semiconductor's commitment to quality ensures that the MC14543BDR2 is a reliable component for long-term use. Its robust design is characterized by high noise immunity, which prevents glitches and errors in the display due to electrical interference. As a result, the MC14543BDR2 is an excellent choice for designers looking for a dependable and efficient solution for driving 7-segment displays.
