74HC174; 74HCT174
Hex D-type flip-flop with reset; positive-edge trigger
Rev. 4 — 12 May 2016
Product data sheet
1. General description
The 74HC174; 74HCT174 are hex positive edge-triggered D-type flip-flops with individual
data inputs (Dn) and outputs (Qn). The common clock (CP) and 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 output. A LOW on MR causes the flip-flops and outputs 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.

For 74HC174: CMOS level
