MC74HC164ADTR2G - 8-Bit Serial-Input/Parallel-Output Shift Register

The MC74HC164ADTR2G is a high-performance, 8-bit serial-input/parallel-output shift register designed by ON Semiconductor. This integrated circuit is part of the 74HC series, which are known for their high-speed CMOS logic family characteristics. The device is particularly suitable for serial-to-parallel data conversion and is widely used in applications such as digital signal processing, data acquisition systems, and automated equipment.

With its advanced silicon-gate CMOS technology, the MC74HC164ADTR2G ensures low power consumption while maintaining high-speed operation. It is capable of operating with a wide range of supply voltages, from 2V to 6V, making it versatile for various digital logic circuits. The device also features a high noise immunity typical of CMOS ICs, which is critical for reliable performance in electrically noisy environments.

The shift register has two serial inputs (A and B), eight parallel output pins (Q0 to Q7), and a clock input. Data is entered serially through the A or B inputs and is shifted through the register on the rising edge of the clock signal. The outputs are updated on the next clock cycle, providing a parallel representation of the serial data. This function allows for efficient expansion of input/output ports using minimal microcontroller pins.

The MC74HC164ADTR2G comes in a TSSOP-14 (Thin Shrink Small Outline Package) form factor, which is beneficial for space-constrained applications. The device also supports a wide operating temperature range, ensuring reliable operation under varying environmental conditions.

Key features of the MC74HC164ADTR2G include:

• 8-bit serial input/parallel output
• Wide operating voltage range (2V to 6V)
• High-speed CMOS technology
• Low power consumption
• High noise immunity
• Compatible with all forms of logic
• Lead-free and RoHS compliant

ON Semiconductor's commitment to quality makes the MC74HC164ADTR2G a reliable choice for designers and engineers looking for a shift register that offers both high performance and durability.
