SN74LV165APWR

The SN74LV165APWR is an 8-bit parallel-load shift register manufactured by Texas Instruments. Designed for versatile operation, it supports a wide VCC range from 2V to 5.5V, making it suitable for various applications. This device features parallel-in access to each stage, enabled by a low level at the shift/load input.

Key electrical characteristics include a maximum propagation delay of 10.5 ns at 5V and a clock frequency of up to 85 MHz. The SN74LV165APWR also supports mixed-mode voltage operation on all ports and includes an Ioff feature for partial power-down mode operation, which disables outputs to prevent damaging current backflow. Latch-up performance exceeds 250 mA per JESD 17.

This shift register is available in a 16-TSSOP package with a body size of 5.00 mm x 4.40 mm. It is designed for surface mount applications and operates within an extended temperature range of -40°C to 125°C. The device functions as a parallel or serial to serial shift register, with 8 bits per element and a single element.

Applications for the SN74LV165APWR include increasing the number of inputs on a microcontroller. Its features like over-voltage tolerant inputs and balanced outputs contribute to its reliability in demanding environments.
