• Qualified for Automotive Applications
• Operating Range 2-V to 5.5-V V
CC
• 8-Bit Serial-In, Parallel-Out Shift
• Shift Register Has Direct Clear
The SN74AHC595 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
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.
Both the shift-register clock (SRCLK) and storage-register clock (RCLK) are positive-edge triggered. If both
clocks are connected together, the shift register always is one clock pulse ahead of the storage register.
