High noise margin 1V guaranteed Tenth power TTL compatible Drive 2 LPTTL loads Wide supply range 3V to 15V Carry and borrow outputs for N-bit cascading Async.
These up down counters are monolithic complementary MOS (CMOS) integrated circuits The MM54C192 and MM74C192 are BCD counters while the MM54C193 and MM74C193 are binary counters Counting up and counting down is performed by two count inputs one being.
