74LS92 Dual 4-Bit Binary Counter IC is a part of the 74XXYY IC series. The 74LS92 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. The IC 74LS92 is smaller in size and it has a much faster speed which makes it reliable in every kind of device.
What is a 4-Bit Decade Counter?
A Binary Counter is a serial digital counter that counts ten digits. it resets for every new clock input. As it can go through 10 unique combinations of output, it is also called as “Decade counter”. A binary counter can count 0000, 0001, 0010, 1000, 1001, 1010, 1011, 1110, 1111, 0000, and 0001 and so on. A 4 bit binary counter will act as a decade counter by skipping any six outputs out of the 16 (24) outputs.
