8-BIT SHIFT REGISTER WITH
3-STATE OUTPUT REGISTERS
DESCRIPTION
The UTC 74AHC595 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.
FEATURES
* Operation Voltage Range: 2~5.5V
* 8-bit Serial-In, Parallel-Out Shift
* Shift Register Has Direct Clear

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
