Overview
The 74LV165D-Q100 is an 8-bit serial or parallel-in/serial-out shift register produced by Nexperia (previously part of NXP USA Inc.). This device is designed to handle both serial and parallel data inputs and outputs. It features a serial data input (DS), eight parallel data inputs (D0 to D7), and two complementary serial outputs (Q7 and Q7'). The device is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications. It operates over a wide supply voltage range from 1.0 V to 5.5 V and is specified for temperatures from -40 °C to +125 °C.
