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 flipflops. Features s Ideal for low power/low noise 3.3V applications s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed pin-to-pin skew AC performance s Guaranteed incident wave switching into 75 Ordering Code: Order Number 74LVQ174SC 74LVQ174SJ Package Number M16A M16D Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide Devices also available in Tape and Reel. Specify by appending suffix letter "X" to the ordering code. Logic Symbols Connection Diagram IEEE/IEC Pin Descriptions Pin Names D0-D5 CP MR Q0-Q5 Description Data Inputs Clock Pulse Input Master Reset Input Outputs (c) 2001 Fairchild Semiconductor Corporation DS011353 www.fairchildsemi.com 74LVQ174 Functional Description The LVQ174 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 LVQ174 is useful for applications where the true output only is required and the Clock and Master Reset are common to all storage elements.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: Unused inputs must be held HIGH or LOW. They may not float.
