Texas Instruments SN74LV8T594/SN74LV8T594-Q1 Shift Registers

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.

The input is designed with a reduced threshold circuit to support up translation when the supply voltage is larger than the input voltage. The 5V tolerant input pins also enable down translation when the input voltage is larger than the supply voltage. The output level always references the supply voltage (VCC) and supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels. The Texas Instruments SN74LV8T594-Q1 devices are AEC-Q100 qualified for automotive applications.
