74HC192 Decade Up/Down Counter with Clear – 74192

74HC192-74192 (Decade Counter) is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. The 74192 is a Presettable Synchronous 4-Bit Up/Down Decade Counter. Presetting the counter to the number on the preset data inputs (Input A – Input D) is accomplished by a LOW asynchronous parallel load input (Load). The counter is incremented on the low-to-high transition of the UP input (and a high level on the Clock- DOWN) and decremented on the low to high transition of the DOWN input (and a high level on the UP input). A high level on the CLR input overrides any other input to clear the counter to its zero state. The Terminal Count up (CO) goes low half a clock period before the zero count is reached and returns to a high level at the zero count. The Terminal Count Down (BO) in the count down mode likewise goes low half a clock period before the maximum count (9 in the 74192) and returns to high at the maximum count. Cascading is effected by connecting the CO [carry] and BO [borrow] outputs of a less significant counter to the Clock-Up [UP] and Clock-Down [DOWN] inputs, respectively, of the next most significant counter. It’s perfect for DIY makers, students, and anyone building custom electronic circuits or STEM kits.
