Each section can be used to add long binary words, one bit on each clock cycle. CRST resets the internal carry flip-flop after one clock delay. The INV inputs can be used to invert the sum output (giving a 1's-complemented result).

4045

21-bit asynchronous binary counter with oscillator and reset input.
Only two 3% duty cycle outputs (180` out of phase) from the last counter stage are available. Can be used to generate a 1Hz clock signal using a 2.097152MHz crystal. P and N MOSFET source connections from the oscillator inverter are brought out of the package to allow the use of source resistors, but usually pS=VCC and nS=GND.
