CD40110 Decade Up/Down Counter

Send Inquiry


The CD40110 is a CMOS Decade Up-down Counter/Latch/Display Driver with a special preconditioning circuit that allows the counter to be clocked, via positive going inputs, up or down regardless of the state or timing of the other clock line. The clock signal is fed into the control logic and Johnson counter after it is preconditioned. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers.
