Product Overview: 74HC590PW by NXP Semiconductors
The 74HC590PW is an advanced high-speed CMOS (Complementary Metal-Oxide-Semiconductor) 8-bit binary counter with output registers and 3-state outputs. Manufactured by NXP Semiconductors, a leader in the semiconductor industry, this integrated circuit (IC) is designed to provide efficient counting and data storage functionality in digital systems. It operates with a 2V to 6V power supply range, making it suitable for a variety of applications across different voltage levels.
The device features an 8-bit counter with a storage register feeding an 8-bit output bus. The counter and output registers have separate positive-edge triggered clock inputs (CP and CP'), which allows them to be used in a flexible manner, such as in frequency division or as a real-time counter. The counter advances on the rising edge of the clock, while the register captures data when the register clock is high. This function is particularly useful for capturing a snapshot of the counter's value at a specific moment in time.
The 74HC590PW also includes a ripple carry output for cascading multiple devices, allowing the creation of counters with many more bits. This feature is essential for applications that require long sequence counting or precise time measurement. The output-enable (OE) input can be used to place the eight outputs in either a normal logic state or a high-impedance state. When in the high-impedance state, the outputs do not interfere with the operation of other components on the bus, which is crucial for bus-oriented systems.
Encased in a TSSOP16 (Thin Shrink Small Outline Package) with a body size of 5.0 mm x 4.4 mm, the 74HC590PW is designed for space-saving on printed circuit boards, without compromising performance and functionality. Its compact form factor and low power consumption make it an ideal choice for portable electronic devices, as well as for general-purpose counting and data storage applications in industrial, automotive, and consumer electronics sectors.
With its robust design and versatile functions, the NXP 74HC590PW is a reliable and practical solution for designers looking to implement counters or timers within their digital systems.
