八D型触发器 Octal D-Type Flip-Flop
The AC273 and ACT273 have eight edge-triggered D-type flip-flops with individual D-type inputs and Q outputs. The common buffered Clock CP and Master Reset MR# input load and reset clear all flip-flops simultaneously.
The register is fully edge-triggered. The state of each D-type input, one setup time before the LOW-to-HIGH clock transition, is transferred to the corresponding flip-flop"s Q output.
All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage level on the MR# input. The device is useful for applications where the true output only is required and the Clock and Master Reset are common to all storage elements.
