ON Semiconductor MC74HC164ADTR2

The MC74HC164ADTR2 is a high-performance, 8-bit serial-input/parallel-output shift register designed by ON Semiconductor, a leading provider of semiconductor-based solutions. This integrated circuit is a part of the high-speed CMOS family and is well-suited for a variety of digital applications where low power operation is essential.

Constructed with silicon gate CMOS technology, the MC74HC164ADTR2 offers the inherent advantages of lower power consumption and wide operating voltage range. It operates over a voltage range of 2V to 6V and features a minimum operating temperature of -55°C, with a maximum of +125°C, making it reliable for use in a diverse array of environments and applications.

The device has two serial data inputs (A and B), eight parallel data outputs (Q0 to Q7), a clock input, and a clear input. The clear input allows for immediate clearing of the register to all zeroes when a high logic level is applied. The serial inputs allow for easy expansion by cascading multiple devices. Data is entered serially through either A or B inputs and shifted out through the parallel outputs with each positive-going clock transition, providing flexibility for serial-to-parallel data conversion.

With its small footprint, the MC74HC164ADTR2 comes in a TSSOP-14 package, which is ideal for space-constrained applications. The device's high noise immunity and low power dissipation make it a robust component for use in digital systems. Furthermore, it is compatible with TTL levels, ensuring easy interfacing with other logic families.

Typical applications for the MC74HC164ADTR2 include serial-to-parallel data conversion, remote control holding registers, and as an interface between microprocessors and LED displays. Its high functionality and reliability make it a versatile choice for designers looking to implement efficient data handling and display functions in their electronic designs.

In summary, the MC74HC164ADTR2 from ON Semiconductor is a versatile, low-power, and reliable shift register that is well-suited for a wide range of digital applications, offering designers a compact solution for serial-to-parallel data conversion.
