Texas Instruments SN74HCS596/SN74HCS596-Q1 8-Bit Serial-In/Parallel-Out Shift Register contains an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. All inputs include Schmitt triggers, which eliminate any erroneous data outputs due to slow-edged or noisy input signals. The storage register has parallel open-drain outputs. Separate clocks are provided for both the shift and the storage register. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and serial output (QH’) for cascading. When the output-enable (OE) input is high, the outputs are in a high-impedance state. The internal register data on the Texas Instruments SN74HCS596/SN74HCS596-Q1 is not impacted by the operation of the OE input. The SN74HCS596-Q1 devices are AEC-Q100 qualified for automotive applications.
