1. General description

The HEF40175B is a quad positive edge triggered D-type flip-flop with four data (Dn) inputs,

common clock (CP) and asynchronous master reset (MR) inputs, and complementary Qn and Qn

outputs. When MR is HIGH data at the D-input that meets the set-up and hold time requirements

on the LOW-to-HIGH clock transition will be stored in the flip-flop and appear at the Q output.

When LOW, MR resets all flip-flops (Qn = LOW, Qn = HIGH), independent of CP and Dn. Inputs

include clamp diodes. This enables the use of current limiting resistors to interface inputs to

voltages in excess of VDD.
