ON Semiconductor MC14543BDR2G Product Overview

The MC14543BDR2G is a high-quality BCD-to-Seven Segment Latch/Decoder/Driver designed by ON Semiconductor, a leading manufacturer in the semiconductor industry. This integrated circuit is specifically engineered to interface with a liquid crystal display (LCD) and is compatible with all ON Semiconductor MC14500B series products. It is a versatile component widely used in applications that require the display of numerical information.

The device includes an on-chip bandgap voltage reference, which ensures stable operation over a wide range of temperatures and power supply variations. It can directly drive a 7-segment LCD with backplanes or other displays with a low multiplex rate. The MC14543BDR2G features a BCD (Binary-Coded Decimal) input structure, which provides a direct connection to the counter and is able to represent the numbers 0 to 9 with just four pins.

With its latch/decoder/driver functions, the MC14543BDR2G offers a simplified method for converting binary-coded decimal data into a format that can be displayed on a seven-segment LCD. The latch allows the device to retain the BCD inputs while the decoder translates this information to the necessary signals for displaying the corresponding numeral on the LCD. The driver then amplifies these signals to the levels required to power the display segments.

The MC14543BDR2G comes in a space-saving SOIC-16 package, making it suitable for compact electronic designs. It operates over a wide supply voltage range from 3 V to 18 V, which provides design flexibility for both low-power and standard applications. It also features phase input to the phase of backplane drive signal, and a blanking input that can be used to control the visibility of the display.

With its low power consumption and high noise immunity, the MC14543BDR2G is an excellent choice for battery-operated devices, industrial control panels, meters, and other consumer electronics that require reliable numerical displays. ON Semiconductor's commitment to quality ensures that this component meets the stringent requirements of the electronic industry, providing both performance and durability.
