Overview
The SN74LV165APWRG3 is a parallel-load, 8-bit shift register designed and manufactured by Texas Instruments. This device operates within a voltage range of 2 V to 5.5 V, making it versatile for various applications. It features a maximum propagation delay of 10.5 ns at 5 V and supports mixed-mode voltage operation on all ports. The SN74LV165APWRG3 is packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package) and is fully specified for partial-power-down applications using Ioff circuitry, which prevents damaging current backflow when the device is powered down.
