DM74LS248

BCD to 7-Segment Decoder with 2 kX Pull-Up Resistors

General Description

The ’LS248 has active HIGH outputs with internal 2 kX pull-

up resistors. It has the same electrical characteristics and

pin connections as the ’LS48. The only difference is that the

’LS248 will light the top bar (segment a) for numeral 6 and

the bottom bar (segment d) for numeral 9. For detailed de-

scription and specifications please refer to the ’LS48 data
