DESCRIPTION

The HEF40175B is a quadruple edge-triggered D-type flip-flop with four data inputs (D0 to D3), a clock input (CP), an overriding asynchronous master reset input (MR), four buffered outputs (O0 to O3), and four complementary buffered outputs (O0 to O3). Information on D0 to D3 is transferred to O0 to O3 on the LOW to HIGH transition of CP if MR is HIGH. When LOW, MR resets all flip-flops (O0 to O3 = LOW, O0 to O3 = HIGH), independent of CP and D0 to D3.
