SN54LS174
SN54LS174 is HEX D FLIP-FLOP manufactured by Motorola Semiconductor.
DESCRIPTION
The LS174 consists of six edge-triggered D flip-flops with individual D inputs and Q outputs. The Clock (CP) and Master Reset (MR) are mon to all flip-flops. Each D input’s state is transferred to the corresponding flipflop’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 LS174 is useful for applications where the true output only is required and the Clock and Master Reset are mon to all storage elements.
