ON Semiconductor MC14511BDR2G BCD-to-Seven Segment Latch/Decoder/Driver

The MC14511BDR2G is a versatile BCD-to-seven segment latch/decoder/driver designed by ON Semiconductor to provide a simple and effective solution for driving seven-segment displays. This integrated circuit (IC) is particularly suited for implementing display interfaces in a wide range of applications, from industrial controls to consumer electronics where numeric information needs to be presented visually.

Constructed with CMOS technology, the MC14511BDR2G offers low power consumption coupled with high noise immunity and stable operation. It is capable of directly driving a seven-segment display with common cathode configuration, making it an ideal choice for designers looking to minimize external components and simplify their designs.

The device features an internal latch, BCD-to-seven segment decoder, and output drive capability. It accepts a 4-bit binary-coded decimal (BCD) input and decodes this to drive a seven-segment display. The latching function allows the display to maintain a stable reading while the input data can be updated. This is crucial for applications where the input data changes rapidly but a steady display readout is necessary.

The MC14511BDR2G is provided in a SOIC-16 package, which is suitable for automated assembly processes and is compatible with a wide range of PCB designs. ON Semiconductor's commitment to quality ensures that this device meets the stringent requirements for industrial and consumer applications.

Key features of the MC14511BDR2G include:

• Operating voltage range of 3V to 18V
• Low power CMOS technology
• Internal latch and decoder to minimize external components
• Direct drive capability for a seven-segment display with common cathode
• Output current capability of 25 mA
• Lamp test and blanking capability to facilitate testing and power-saving modes

This IC is ideal for applications such as digital clocks, electronic meters, calculators, and any other system requiring numeric displays. The MC14511BDR2G's combination of features and ease of use makes it a go-to component for engineers and designers looking to enhance the user interface of their products with reliable and clear numeric displays.
