The TC74HC590AP is an 8-bit binary counter manufactured by Toshiba Semiconductor and Storage. This high-speed CMOS counter integrates advanced silicon gate CMOS technology to achieve the high-speed operation similar to equivalent Bipolar Schottky TTL, while maintaining the low power CMOS dissipation. It consists of an 8-bit binary counter, a 3-state 8-bit register and control circuitry for the counter and register. This allows for versatile applications where counting and storage of binary data are required.
