Product Overview: SN74LV165ADG4 by Texas Instruments

The SN74LV165ADG4 is a high-performance, 8-bit parallel-load shift register designed and manufactured by Texas Instruments, a leader in semiconductor innovation. This integrated circuit is part of the 74LV family, which operates at lower voltages with better performance than the standard 74 series, making it suitable for battery-operated and low-power applications.

Engineered for optimal efficiency, the SN74LV165ADG4 operates within a voltage range of 2V to 5.5V, which allows for use in systems that require a wide operating voltage range. The low-power consumption of the device is a significant advantage for portable and power-sensitive designs.

This shift register features an 8-bit serial or parallel input and a serial output format. It is capable of performing serial-to-parallel conversion with clocked serial shifting on the positive-going transition of the clock input while the asynchronous reset clears the register, setting all outputs low. The parallel load inputs are active on the falling edge of the shift/load (SH/LD) input.

The SN74LV165ADG4 offers a direct overriding clear (CLR) input, which is synchronous with the clock, and a clock input that is gated by the clock enable (CLK INH) input. This gating feature allows for better control of the clock signal, which is essential for precise data manipulation and timing-sensitive applications.

With its wide operating temperature range from -40°C to 85°C, the SN74LV165ADG4 is robust and reliable, making it suitable for industrial and automotive applications where extreme conditions may be encountered. The device is available in a compact 16-pin SOIC package, which is ideal for space-constrained applications.

Overall, the SN74LV165ADG4 from Texas Instruments is a versatile and reliable component that provides a convenient solution for expanding the input/output capabilities of microcontrollers, enhancing the efficiency of data acquisition systems, and simplifying the design of complex digital circuits.
