74HC174; 74HCT174

Hex D-type flip-flop with reset; positive-edge trigger

Rev. 6 — 1 September 2021

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 V_CC

2. Features and benefits
