SN74LS590NS TI Counter Register | 8-Bit, 3-State, 20MHz

Product Overview

The SN74LS590NS is a high-performance 8-bit binary counter with output registers and 3-state outputs from Texas Instruments. It integrates a counter and a storage register in a single package, allowing data to be transferred from the counter to the register while counting continues. The device operates from a 4.75V to 5.25V supply and features a typical clock frequency of 20 MHz. Housed in an SOP-20 package, it is ideal for applications requiring parallel data storage and counting.
