CD40193 Presettable 4-Bit Binary Up/Down Counter DIP-16 (CD40193 DIP IC)
The CD40193 is a high-voltage CMOS 4-bit binary synchronous up/down counter that features separate clock inputs for counting up and counting down. It is designed with a parallel load facility that allows the counter to be preset to any 4-bit binary number and an asynchronous master reset for clearing the count.
This IC is widely used in digital frequency synthesizers, programmable timers, and high-speed binary counting applications. It is a staple in Arduino electronics projects in India for creating reversible counters, digital volume controls, and multi-stage binary division circuits.
