ACT174

The ACT174 is a high-speed hex D-type flip-flop. The device is used primarily as a 6-bit edge-triggered storage register. The information on the D inputs is transferred to storage during the LOW-to-HIGH clock transition. The device has a master reset to simultaneously clear all flip-flops. The ACT174 consists of six edge-triggered D-type flip-flops with individual D inputs and Q outputs. The Clock(CP) and Master Reset (MR) are common to all flip-flops. Each D input's state is transferred to the corresponding flip-flop's output following the LOW-to-HIGH Clock (CP) transition. A low input to the master reset (MR) will force all outputs low independent of clock or data inputs. The ACT174 is useful for applications where the true output only is required and the clock and master reset are common to all storage elements.

The features of ACT174 can be summarized as (1)ICC reduced by 50%; (2)outputs source/sink 24 mA; (3)ACT174 has TTL-compatible inputs.
