MM74C193N Datasheet PDF - Fairchild

●General Description

●The MM74C192 and MM74C193 up/down counters are monolithic complementary MOS (CMOS) integrated circuits. The MM74C192 is a BCD counter, while the MM74C193 is a binary counter.

●Counting up and counting down is performed by two count inputs, one being held high while the other is clocked. The outputs change on the positive-going transition of this clock.

●Features

●■ 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

●■ Asynchronous clear

●■ High noise immunity: 0.45 VCC (typ.)
