Hitachi -> Renesas Electronics 

HD74AC166/HD74ACT166

8-bit Shift Register

Description

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.

The circuit can be clocked from two sources or one CP input can be used to trigger the other.

Features

• Outputs Source/Sink 24 mA

• HD74ACT166 has TTL-Compatible Inputs
