The SN74LS247DR is a BCD-to-7-segment LED driver from the 74LS family, built for driving common-cathode LED displays directly from TTL logic levels. The 4.75V to 5.25V supply rail matches standard 5V digital buses; the 7 mA supply current covers the internal logic and output sink drivers, not the LED segment current itself.
No — the CD74HCT4511E is a through-hole part in a DIP package, while the SN74LS247DR is surface-mount 16-SOIC. Both accept BCD input and drive 7-segment LED displays, but the package difference means a board layout change is required. The supply voltage ranges also differ: the 74LS family runs on 4.75-5.25V, while the 74HCT version operates down to 4.5V.
