3 Description
The SN74AHC165 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 registers. The shift register has
a direct overriding clear (SRCLR) input, a 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.
