Overview
The SN74LS247NSR is a BCD-to-seven-segment decoder and driver manufactured by Texas Instruments. It accepts Binary-Coded Decimal inputs and drives common-anode seven-segment displays. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to +70°C. It utilizes a 16-pin Small Outline Package (SOIC) with a tape-and-reel configuration for surface-mount assembly.
Feature Summary
- Converts four-bit binary-coded decimal data into signals suitable for driving common-anode seven-segment displays.
- Includes dedicated lamp test and ripple blanking input/output functions for display control and diagnostics.
Applications
- Digital numeric display systems
- Seven-segment indicator panels
- Consumer electronic devices requiring decimal readouts
Procurement Notes
Verify the specific suffix 'NSR' confirms the SOIC-16 package and tape-and-reel shipping format. Ensure compatibility with common-anode display configurations, as this component is not designed for common-cathode setups. Confirm that the LS logic family requirements align with the target system's power and speed specifications before finalizing procurement.
Selection Notes
Select this component when a standard TTL-compatible BCD-to-decimal conversion is required for visual output. It is appropriate for designs utilizing common-anode LED or LCD segments. Consider the SOIC-16 footprint for space-constrained printed circuit board layouts. Verify that the drive current capabilities meet the segment requirements of the selected display unit.
Part Context
This part belongs to the Texas Instruments SN74LS series, representing low-power Schottky TTL logic. The SN74LS247 variant specifically addresses the need for direct interface between digital logic circuits and alphanumeric visual indicators. It serves as a bridge between microprocessor outputs and human-readable display hardware.
Replacement Considerations
The SN74LS247N is a pin-compatible through-hole alternative offering identical logical functionality in a DIP-16 package. Designers transitioning from surface-mount to through-hole technologies may utilize this substitution without modifying the circuit schematic.
