ON Semiconductor MC14543BCP Product Overview

The MC14543BCP is a versatile BCD-to-Seven Segment Latch/Decoder/Driver designed and manufactured by ON Semiconductor, a leader in energy-efficient electronics innovation. This integrated circuit (IC) is specifically engineered to directly interface with a seven-segment display. It is commonly utilized in digital clock applications, electronic meters, and other devices that display numerical output.

This high-performance IC is built to operate with a 3V to 18V supply voltage range, making it suitable for a wide array of applications from low-voltage portable devices to standard industrial equipment. The MC14543BCP features latched binary coded decimal (BCD) inputs and provides outputs that are designed to drive common-cathode seven-segment displays.

The device includes an on-chip bandgap voltage reference which is temperature-compensated and offers stable operation over its full operating temperature range. The MC14543BCP's internal circuitry ensures that the decoded output remains stable throughout the entire supply voltage range, providing reliable performance in a variety of environmental conditions.

Key Features of the MC14543BCP:

• Directly drives 7-segment common-cathode LED displays
• Wide supply voltage range: 3V to 18V
• Temperature-compensated voltage reference
