3 Description
The SN74AHCT165-Q1 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.
