Texas Instruments SN74LV594A/SN74LV594A-Q1 Serial Shift Registers

Texas Instruments SN74LV594A/SN74LV594A-Q1 8-Bit Parallel-Out Serial Shift Registers are designed for 2V to 5.5V VCC operation. The SN74LV594A-Q1 is AEC-Q100 qualified for automotive applications and is available in a wettable flank QFN (WBQB) package. The TI SN74LV594A/-Q1 provides direct overriding that clears on shift and storage registers.
