Overview
The SN74LV165ADRG3, produced by Texas Instruments, is a parallel-load, 8-bit shift register designed for operation over a wide voltage range of 2 V to 5.5 V. This device is part of the 74LV series and is housed in a 16-pin SOIC package. It features a clock-inhibit function and a complemented serial output, QH. The shift register allows for parallel-in access to each stage via eight individual direct data inputs, which are enabled by a low level at the shift/load (SH/LD) input. This makes it versatile for various digital circuit applications.
