SN74LS247N

Overview

The SN74LS247N is a BCD-to-7-segment decoder and driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and consumes 7mA of current. The device features TTL-compatible inputs and outputs, supporting operation across a temperature range of 0°C to 70°C. It is housed in a 16-pin PDIP package with a width of 0.300 inches (7.62mm).

Feature Summary

• Converts binary-coded decimal inputs into signals for seven-segment displays.
• Features active-low outputs designed for common-anode LED configurations.
• Includes built-in blanking functionality to control display visibility.

Applications

• Driving seven-segment LED numeric displays.
• BCD decoding circuits in digital instrumentation.
• Data display interfaces in consumer electronics.

Procurement Notes

Verify the specific manufacturer source, as this component is produced by multiple vendors including Motorola/NXP. Confirm RoHS compliance status, as some variants may not meet current environmental standards. Ensure the package type matches the required 16-pin DIP footprint for your PCB layout.

Selection Notes

Select this component when a dedicated BCD-to-7-segment decoder is required for driving common-anode displays. It is suitable for standard TTL logic families operating at 5V. Consider alternative drivers if high-current output or common-cathode compatibility is needed.

Part Context

This part belongs to the SN54/74LS247/48 series, which includes related decoder and driver devices. It is part of the broader LS logic family known for low-power Schottky performance. The device serves as a specialized interface between digital logic systems and visual output components.
