SN74LV164ADGVR - Texas Instruments 8-Bit Serial-In, Parallel-Out Shift Register

The SN74LV164ADGVR from Texas Instruments is a high-performance, 8-bit serial-in, parallel-out shift register designed to operate with a wide supply voltage range from 2 V to 5.5 V. This device is part of the 74LV family, which is known for its low-voltage operation and low power consumption, making it an ideal choice for battery-operated and portable applications.

With its compact TVSOP (Thin Shrink Small Outline Package) design, the SN74LV164ADGVR is particularly suited for space-constrained applications. It features two serial data inputs (A and B) that allow for either single or parallel clocking, providing designers with flexibility in controlling the flow of data. The outputs are designed to drive loads directly without the need for external current-limiting resistors, thus simplifying design and reducing component count.

This shift register is capable of operating at clock frequencies up to 50 MHz, ensuring high-speed data transfer and processing. The clear function is synchronous, which means it is activated on a low level at the clear input (CLR) while the clock input (CLK) is high. This allows for the register to be cleared in a controlled manner during normal operation.

The SN74LV164ADGVR is widely used in a variety of digital systems for expanding the number of outputs in microcontroller-based projects, driving LEDs, and for serial-to-parallel data conversion. Its robust design ensures reliable operation over the extended industrial temperature range of -40°C to 85°C, making it suitable for harsh environments.

Key features of the SN74LV164ADGVR include:

• 8-bit serial-in, parallel-out shift register
• Wide operating voltage range: 2 V to 5.5 V
• High clock frequency: up to 50 MHz
