Texas Instruments SN74LV8T594/SN74LV8T594-Q1 8-Channel Shift Registers contain an 8-bit, serial-in, parallel-out shift register. Each parallel output of the shift register is fed through a storage register before reaching the primary device outputs (QA through QH). Separate clocks (SRCLK and RCLK) and direct overriding clear (SRCLR and RCLR) inputs are provided for both the shift and storage registers, allowing data to be loaded separately from sending it to the outputs. Additionally, the last output of the internal shift register is sent directly to the output QH’ providing a method to daisy-chain multiple shift registers.
