DM74LS247
BCD to 7-Segment Decoder/Driver with Open-Collector
Outputs
General Description
The ’LS247 has active LOW open-collector outputs guaran-
teed to sink 24 mA. It has the same electrial characteristics
and pin connections as the ’LS47. The only difference is that
the ’LS247 will light the top bar (segment a) for numeral 6
and the bottom bar (segment d) for number 9. For detailed
description and specifications please refer to the ’LS47 data
sheet.
