CD40193BC Datasheet - National Semiconductor

CD40193BC Synchronous 4-Bit Up/Down Decade Counter

These up down counters are monolithic complementary MOS (CMOS) integrated circuits The CD40192BM and CD40192BC are BCD counters while the CD40193BM and CD40193BC are binary counters Counting up and counting down is performed by two count inputs one being held high while the other is clocked The outp.
