Bcd-to-seven-segment Decoders/drivers , Inc

The SN54LS247 SN54LS248 SN54LS249 SN74LS247 SN74LS248 SN74LS249 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 LS47, 48 and 49. The LS47 thru 49 compose the and without tails, the LS247 thru 249 compose the and with the tails. The LS247 has active-low outputs for direct drive of indicators. The LS248 and 249 have active-high outputs for driving lamp Buffers By Freescale Semiconductor, Inc
