Product Summary
The SN74AHC595PWR is an 8-bit shift register with 3-state output register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift and storage registers. The shift register has a direct overriding clear (SRCLR) input, serial (SER) input, and a serial output for cascading. When the output-enable (OE) input is high, all outputs, except QH, are in the high-impedance state.
