SN74LS90N Counter/Divider Single 4-Bit Decade UP 14-Pin PDIP Tube
Decade and Binary Counters Features: High-speed Operation Synchronous Counting and Loading Synchronous Master Reset Ripple-Carry Output Outputs Source/Sink 24 mA TTL-Compatible Inputs and Outputs Input Clamping Diodes Common Reset Common Clock Application: The SN74LS90N is a high-speed synchronous decade and binary counters. It is designed for use in frequency division, counting, and time delay applications. It can be used to divide the frequency of a clock signal by any number between 2 and 1023. It can also be used to count the number of pulses on an input signal. The SN74LS90N is ideal for use in digital systems where high-speed operation, low power consumption, and low noise are required.
