STMicroelectronics M74HC590TTR 8-bit Binary Counter with Output Register and 3-State Outputs
The M74HC590TTR from STMicroelectronics is a high-speed CMOS 8-bit binary counter with an output register and 3-state outputs designed for use in microprocessor systems and a variety of other digital applications. This integrated circuit is part of the HC family, which ensures a high noise immunity and the ability to operate at low power levels, making it suitable for battery-operated devices and power-sensitive applications.
One of the key features of the M74HC590TTR is its two distinct sections: an 8-bit binary counter and an 8-bit storage register. The counter advances on the rising edge of the clock (CLK) input, while the register captures the data from the counter when the register clock (RCO) input is activated. This allows for seamless data transfer and synchronization within digital systems.
The device also includes a carry output for cascading multiple counters, which is useful in applications requiring extended counting sequences. Additionally, the 3-state output control (OC) feature provides a means to place the eight outputs in a high-impedance state. This is particularly beneficial when the outputs are connected to a common data bus, as it allows for multiple devices to share the same bus without interference.
The M74HC590TTR operates over a wide voltage range from 2V to 6V and is characterized for operation from -55°C to +125°C, ensuring reliability across various environmental conditions. The counter's inputs are compatible with TTL levels, making it easy to interface with other logic families.
This product comes in a TSSOP16 package, which is ideal for space-constrained applications. Its surface-mount design allows for efficient assembly in automated production lines and contributes to the miniaturization of electronic systems.
Whether you're designing a sophisticated microprocessor system or a simple digital counter, the M74HC590TTR offers a robust and flexible solution for your counting and data storage needs. Its high integration, combined with STMicroelectronics' reputation for quality, makes it a smart choice for your next project.
