The SN54SC8T595-SEP device 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 outputs are in a high-impedance state. Internal register data is not impacted by the operation of the OE input. The output level is referenced to the supply voltage (VCC) and supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels.
The input is designed with a lower threshold circuit to support up translation for lower voltage CMOS inputs (for example, 1.2V input to 1.8V output or 1.8V input to 3.3V output). In addition, the 5V tolerant input pins enable down translation (for example, 3.3V to 2.5V output).
