CD40193 Datasheet PDF - Fairchild

●General Description

●The CD40192BC and CD40193BC up/down counters are monolithic complementary MOS (CMOS) integrated circuits. The CD40192BC is a BCD counter, while the CD40193BC 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

●■Wide supply voltage range: 3V to 15V

●■High noise immunity: 0.45 VDD(typ.)

●■Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS

●■Carry and borrow outputs for easy expansion to N-bit by cascading

●■Asynchronous clear

●■Equivalent to: MM74C192 and MM74C193
