Texas Instruments SN74LV8T165/SN74LV8T165-Q1 8-Bit Shift Registers

Texas Instruments SN74LV8T165/SN74LV8T165-Q1 Parallel-Load 8-Bit Shift Registers are parallel- or serial-in, serial-out 8-bit shift registers. These devices have two modes of operation: load data and shift data, which are controlled by the SH/LD input. The output level supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels and references the supply voltage (V_CC).

The input is designed with a lower threshold circuit to support up translation for lower voltage CMOS inputs (for example, 1.2V input to 1.8V output or 1.8V input to 3.3V output). In addition, the 5V tolerant input pins enable down translation (for example, 3.3V to 2.5V output). The Texas Instruments SN74LV8T165-Q1 devices are AEC-Q100 qualified for automotive applications.
