CD4040BE CD4040 CMOS 12-Stage Ripple-Carry Binary Counter/Divider Breadboard-Friendly IC DIP-16 (Pack of 20)

The CD4040B are ripple-carry binary counters. All counter stages are master-slave flip-flops. The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets the counter to its all zeros state. Schmitt trigger action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered.

• Medium-speed operation, Fully static operation
• Buffered inputs and outputs, 100% tested for quiescent current at 20 V, Standardized, symmetrical output characteristics
