SN74LS247 BCD-TO-SEVEN-SEGMENT DECODERS/DRIVERS

BCD-TO-SEVEN-SEGMENT DECODERS/DRIVERS The SN54/74LS247 thru SN54/74LS249 are BCD-to-Seven-Segment Decoder/Drivers. The LS247 and LS248 are functionally and electrically identical to the LS47 and LS48 with the same pinout configuration. The LS249 is a 16-pin version of the 14-pin LS49 and includes full functional capability for lamp test and ripple blanking which was not available in the LS49. The composition of all characters, except the 6 and 9 are identical between the LS247, 248, 249 and the .
