The HD74AC166/HD74ACT166 is an 8-bit, serial or parallel-in, serial-out shift register using edge triggered D-type flip-flops.

Serial and parallel entry are synchronous, with state changes initiated by the rising edge of the clock.

An asynchronous Master Reset overrides other inputs and clears all flip-flops.

HD74AC166/HD74ACT166 8-bit Shift Register.

Outputs Source/Sink 24 mA.
