1. General description
The 74HC174; 74HCT1 74 are hex po sitive edge -triggered D-type flip-flop s with individual
data inputs (Dn) and outputs (Qn). The common clock (CP) an d master reset (MR ) inputs
load and reset all flip-flops simultaneously. The D-input that meets the set-up and hold
time requirements on the LOW-to-HIGH clock transition is stored in the flip-flop and
appears at the Q outpu t. A LOW on MR causes the flip-flop s and output s to be reset LOW.
Inputs include clamp diodes. This enables the use of current limiting resistors to interface
inputs to voltages in excess of VCC.
2. Features and benefits

For 74HC174: CMOS level
