The 74LS90, a product from Panasonic Electronic Components, is a versatile 14-pin decade counter IC. It is specifically designed to count occurrences from 0 to 9 and then reset to 0, providing a 4-bit binary output. This chip integrates a divide-by-2 and a divide-by-5 counter, allowing for a total divide-by-10 function when configured correctly.
This component typically operates at a 5V VCC supply. The 74LS90 can source up to 0.8 mA and sink up to 16 mA from its output pins. Its functionality makes it suitable for various digital counting applications, including the construction of digital clocks and frequency counters.
The 74LS90 is housed in a standard 14-pin package, commonly mounted using through-hole techniques. Proper power connections to VCC and GND are essential for its operation. The chip includes dedicated inputs for clock pulses and reset/set functions to control its counting sequence.
