Overview
The 74LV165PW,118 is an 8-bit parallel-in/serial-out shift register produced by Nexperia USA Inc. This device is designed to operate in both parallel and serial modes, making it highly versatile for various applications. It features a serial data input (DS), eight parallel data inputs (D0 to D7), and two complementary serial outputs (Q7 and Q7'). The shift register can load data asynchronously from the parallel inputs when the parallel load input (PL) is LOW, and it shifts data serially at the DS input when PL is HIGH. The clock enable input (CE) controls the shifting of data on the LOW-to-HIGH transitions of the CP input.
The 74LV165PW,118 is optimized for low-voltage applications, with a wide supply voltage range from 1.0 V to 5.5 V, and it supports CMOS low power dissipation. It also has direct interface capability with TTL levels between 2.7 V and 3.6 V. The device is packaged in a 16-lead TSSOP (Thin Shrink Small Outline Package) and operates over a temperature range of -40°C to 125°C.
