ON Semiconductor MC74HC164BDR2G
The MC74HC164BDR2G is a high-performance, 8-bit serial-in/parallel-out shift register produced by ON Semiconductor. This integrated circuit is designed to interface directly with high-speed system buses and is fabricated with silicon gate CMOS technology. It boasts a significant advantage in that it requires a low input current, making it ideal for battery-operated and low-power applications.
This shift register features two serial data inputs (A and B), which allow for parallel or serial input modes. The eight parallel outputs (Q0 to Q7) are available on the chip, providing a versatile interface for a wide range of applications. The device operates over a broad voltage range from 2V to 6V and offers a high noise immunity characteristic of CMOS devices. The MC74HC164BDR2G is capable of driving up to 10 LSTTL loads, which makes it highly compatible with traditional TTL logic levels.
One of the key features of the MC74HC164BDR2G is its Schmitt-triggered clock input. This feature allows for enhanced stability and noise immunity, making the device reliable in environments with electrical noise. Additionally, the chip includes a clear function, which is synchronous to the clock input. This allows for the simultaneous clearing of the entire register, ensuring a rapid return to a known state whenever necessary.
The MC74HC164BDR2G is provided in a compact SOIC-14 package, making it suitable for space-constrained applications. The device's pin configuration is thoughtfully designed for easy PCB layout and efficient signal routing. Its operating temperature range from -55°C to +125°C ensures reliable performance across a wide range of environmental conditions.
Common applications for the MC74HC164BDR2G include digital data processing, signal processing, and control systems where efficient data transfer is required. Its high-speed operation, low power consumption, and robust feature set make it a preferred choice for designers looking to implement serial-to-parallel data conversion within their electronic projects.
