Texas Instruments SN74HCT595/SN74HCT595-Q1 8-Bit Shift Register

Texas Instruments SN74HCT595/SN74HCT595-Q1 8-Bit Shift Register contains an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift and storage register. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and a serial output (QH’) for cascading. When the output-enable (OE) input is high, the storage register outputs are in a high-impedance state. Internal register data and serial output (QH’) are not impacted by the operation of the OE input. The Texas Instruments SN74HCT595-Q1 devices are AEC-Q100 qualified for automotive applications.
