SN74LS247N (74LS247) Logic chip
Description:
The SN74LS247N integrates internal logic to decode four lines of BCD (Binary-Coded Decimal) data into the 7-segment format. It is capable of directly driving a common-cathode LED display or other types of 7-segment displays through its outputs, which correspond to each segment of the display.
Key Features:
- BCD to 7-segment decoder/driver
- Direct drive for common-cathode LED displays
- Internal pull-up resistors on inputs
- Operating voltage: 4.75V to 5.25V
- Low power consumption
