74LS47 BCD to 7-Segment Decoder/Driver IC

The 74LS47 is a BCD to 7-Segment Decoder/Driver IC designed to convert Binary Coded Decimal (BCD) inputs into a format suitable for driving 7-segment displays. This IC features open-collector outputs and is capable of directly driving the segments of a 7-segment display with high current sink capability. It is an ideal solution for applications that require easy-to-read numeric displays, such as in digital clocks, counters, and other devices.

Key Features:

• BCD to 7-Segment Decoding: Accepts four lines of BCD (8421) input data and decodes them into 7-segment display data.
• Open Collector Outputs: Outputs are open collector, allowing the IC to drive the display segments directly without the need for additional drivers.
• High Current Sink Capability: Each output segment can sink up to 24 mA in the ON (LOW) state, ensuring reliable illumination of the 7-segment display.
• High Voltage Tolerance: The outputs can withstand up to 15V in the OFF (HIGH) state with a maximum leakage current of 250 µA, making the IC robust and reliable in various applications.
• Auxiliary Blanking Inputs: Includes inputs for blanking control, allowing for the suppression of leading or trailing zeroes.
• Standard TTL Switching Voltages: Compatible with standard TTL logic levels for easy integration into digital systems.
• Operating Temperature: Designed to operate within a temperature range of 0°C to 70°C.

Important Notes:

• Superseded, Not Recommended for New Designs: While the 74LS47 is a reliable and widely used IC, it has been superseded by more modern ICs and is not recommended for new designs.
• Product Images: Product images shown for illustrative purposes only; actual products may differ slightly in appearance.

Package Includes:

• 1 x 74LS47 BCD to 7-Segment Decoder/Driver IC
  • Package Type: DIP-16 Package

The 74LS47 is a versatile and efficient decoder/driver IC for driving 7-segment displays in a variety of applications. Despite being superseded for new designs, it remains a valuable component for existing systems and for those looking for cost-effective solutions in legacy projects.
