3 Description

The SN74AHC165-Q1 device contains an 8-bit serialin,

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.
